CLARK, Circuit Judge:
A warrantless search of defendant’s airplane disclosed the marijuana on which his convictions were based. Its validity is the only issue on appeal. Our rejection of the district court’s rationale that the airport at which the search occurred was the functional equivalent of the border requires that we examine the authority of the searching Customs agent. Having concluded that, after
United States v. Almeida-Sanchez,
413 U.S. 266, 93 S.Ct. 2535, 37 L.Ed.2d 596 (1973), Customs agents possess no authority to search on less than probable cause at points removed from the border or its functional equivalent, we have reviewed the facts and circumstances which led to the search to determine whether probable cause and exigent circumstances existed to justify the officers’ actions. This final analysis reveals that the search was good, and the convictions are affirmed.
I.
On April 22,1976, Drug Enforcement Administration (DEA) agent Dennis Fitzgerald received a telephone call from Douglas Dufresne, a Pan American World Airways pilot. Dufresne told Fitzgerald that he had information leading him to suspect that John J. Brennan “was going to engage in some smuggling activities into the Melbourne Regional Airport.” Prior to the call, Fitzgerald had had no dealings with Dufresne and had never heard of Brennan.
On April 25, Fitzgerald and another DEA agent met with Dufresne at his residence. At this meeting, Dufresne described Brennan’s plane as a 1969 twin engine Beagle, blue and gold in color, with tail number N569MA, and told the agents that the aircraft was kept in a hangar at the Melbourne Regional Airport. He also recounted a trip to Colombia he had made with Brennan in November 1974, during Which the two of them had been arrested by Colombian police and kept in jail for about a month. After investigation and court proceedings, all charges were dropped, and Brennan and Dufresne were allowed to leave Colombia. Dufresne never disclosed the basis, if any, for the arrest and detention. Finally, Dufresne told the agents he suspected that Brennan would install a 55-gallon auxiliary fuel tank in the Beagle to enable him to make a flight to Colombia and back without refueling and that the purpose of the trip would be to smuggle in 1600 or 1700 pounds of marijuana. Dufresne’s load estimate was based on his own guess as to the plane’s capacity and not on anything Brennan had told him.
On April 28, 1975, Dufresne called Fitzgerald and reported that he had recently talked to Brennan by phone and inferred from the conversation that the smuggling trip would take place within the next two or three weeks. Dufresne stated to Fitzgerald that this inference was based on Brennan’s purchase of the plane and insurance for it in the amount of $95,000 at a time when he, Dufresne, had personal knowledge that Brennan was experiencing great difficulty in meeting the day-to-day living expenses of his family. When Dufresne asked Brennan about his expensive purchase, the latter had replied, “I am just doing my thing.” Brennan had also requested that Dufresne try to locate a second-hand loran — an overwater navigational device suitable for ship or aircraft
use. Brennan had said the loran was for “his brother’s boat.”
Fitzgerald confirmed that aircraft N569MA was hangared at the Melbourne Regional Airport. When he contacted the American Embassy in Colombia to investigate the November 1974 arrest of Brennan and Dufresne, he learned that three suspected smugglers, Richard H. Silkie, James King, and Richard Ferrara, had been jailed at the same time, but further investigation failed to establish any relationship between Brennan, Dufresne and the three or what charges had been made against Brennan and Dufresne. The El Paso Intelligence Center was notified to put the tail number of the aircraft into its computer which was used to collect and report possible smuggling-related flight activity.
On May 17, 1975, at approximately 11:00 a. m., Fitzgerald received word that the Beagle aircraft had taken off from Melbourne and was headed in a southwesterly direction. Alleged radar contact with the plane was lost when it entered the air traffic pattern over Miami.
Fitzgerald contacted Customs officers headquartered at Tampa, advised them of the Dufresne tips and the flight of N569MA, and requested assistance. An estimated 6 to 7 hours later, two Customs agents, Hays and Miller, were dispatched to the Melbourne airport; they arrived at 5:00 p. m. At approximately 1:30 a. m. on the morning of May 18, the Customs agents sighted a Beagle aircraft moving along the taxiway leading to the hangar normally occupied by the Brennan plane and identified it as N569MA. The plane taxied to the door of the hangar, at which time the agents drove their van to another location near the hangar. During this time, a white male later identified as Brennan exited the hangar and headed toward his nearby automobile. Upon encountering a Melbourne police officer, Brennan headed back toward the hangar, where he was detained by DEA agents. Agent Hays entered the hangar through its partially open door and approached the plane. Observing through the window of the airplane a number of tightly wrapped packages characteristically used to transport marijuana, he decided to conduct a full search of the plane, which disclosed 60 packages of marijuana totaling approximately 1600 pounds and one bundle containing 466 grams of hashish. Following this discovery, Brennan was arrested.
After a hearing at which this testimony was developed, the district court denied the motion to suppress, ruling that the Melbourne airport is the functional equivalent of the border “with regards to those aircraft actually arriving from outside the United States.” The district court characterized the test to be applied to the facts in making the determination of functional equivalency was “whether there was reasonable cause to believe that defendant’s plane did in fact arrive from outside the United States.” Finally, in applying that test, the court found that “[cjonsidering all factors involved, including the information given the government agents by the confidential informant who had been in close contact with the defendant,” reasonable cause existed for such a belief.
II.
This court must first determine whether the district court was correct in deciding that the search took place at the functional equivalent of the border. If so, the agents were entitled to conduct a full search for contraband without particularized knowledge of what Brennan or his plane was carrying.
Almeida-Sanchez v.
United States,
413 U.S. 266, 272-273, 93 S.Ct. 2535,2539, 37 L.Ed.2d 596 (1973);
Carroll v. United States,
267 U.S. 132, 154, 45 S.Ct. 280, 285, 69 L.Ed. 543 (1925). No warrant or showing of probable cause is required to support such searches. The national interests in self-protection and protection of tariff revenues authorize a requirement that persons crossing the border identify themselves and their belongings as entitled to enter and be subject to search.
In writing for the court, Justice Stewart did not define the “functional equivalent” phrase; instead he gave illustrative examples:
For example, searches at an established station near the border, at a point marking the confluence of two or more roads that extend from the border, might be functional equivalents of border searches. For another example, a search of the passengers and cargo of an airplane arriving at a St. Louis airport after a nonstop flight from Mexico City would clearly be the functional equivalent of a border search.
United States v. Almeida-Sanchez, supra,
413 U.S. at 272-73, 93 S.Ct. at 2539. In the first example there inheres a high degree of probability that a border crossing took place and an attendant likelihood that nothing about the object of the search has changed since the crossing. The location of the checkpoint according to the criteria customarily employed by ranking Border Patrol officials minimizes the uncertainty, and statistical study of those passing through the checkpoint gives both the officers on the scene and the reviewing courts a benchmark against which to measure it.
In the case of the airport search of the nonstop flight, both assumptions become certainties. Thus, as Justice Stewart pointed out, the search of the nonstop flight “would clearly be” a search at the functional equivalent of the border, whereas a search at a checkpoint “might be” — if the facts and circumstances with respect to the location provided the necessary degree of certainty that persons and objects passing through that location were entering the country unchecked. At
Almeida’s
“functional equivalent,” there neither is nor need be any evidence pointing to specific persons as “suspects” before they pass through the location.
The Melbourne Regional Airport was not the functional equivalent of the border when Brennan’s plane landed and taxied into its hangar. Two factors lead us to this conclusion. First, international flights make up only a small percentage of the traffic at the airport, and there was no attempt by airport officials to screen and separate international flights at takeoff and landing.
While it is true that a nonstop flight arriving from outside the country “brings the border with it,” the facts here do not furnish any reliable indication that Brennan’s flight was international. He filed no flight plan and his only known direction of travel led toward a metropolitan center in south Florida. The assumed international origin, which was crucial in Justice Stewart’s nonstop flight example, is simply too attenuated here to support this search as one occurring at a functional equivalent of an international border. Second, the regularity factor emphasized in
United States v.
Martinez-Fuerte, -U.S. -, 96 S.Ct. 3074, 48 L.Ed.2d-(1976), is absent here. At a ground traffic checkpoint, at the end of a ship’s gangplank, or at an established Customs station, each encounter between private citizen and public official begins in substantially the same way. The intrusion is minimal, the existence and function of the checkpoint is known to the citizen in advance of his entry into its lanes, there is little discretionary
enforcement activity, and the results of the checking procedure may be reviewed by the courts without distortion of the issue of reasonableness by hindsight knowledge that the search produced the desired fruits, if any, of the stop or search.
See United States v. Martinez-Fuerte,
supra,-U.S. at-, 96 S.Ct. at 3082. By contrast, the operation here involved a full search, was not anticipated by the subject, involved discretionary decisions at several levels of authority, and was so particularized to the suspicions of defendant’s activities that the success of the search clearly cast an aura of reasonableness on the encounter itself. In sum, this search did not possess the characteristics of a border search or other regular inspection procedures. It more resembled the common nonborder search based on individualized suspicion, which must be prefaced by the usual warrant and probable cause standards, unless the authority of the searching officials is not controlled by
Almeida-Sanchez.
III.
Thus, the next question is whether the Customs officials involved, because of their status, possessed the authority to search Brennan’s plane for contraband at the Melbourne airport without probable cause or a warrant.
This portion of our review must confront the question reserved in
United States v. Freund,
525 F.2d 873 (5th Cir. 1976),
cert.
denied, -- U.S. -, 96 S.Ct. 2631, 49 L.Ed.2d 377;
United States v. Soria,
519 F.2d 1060 (5th Cir. 1975): to what extent is the law of
Customs
searches affected by the Supreme Court’s decisions in
Almeida-Sanchez v. United States,
413 U.S. 266, 93 S.Ct. 2535, 37 L.Ed.2d 596 (1973), and subsequent cases involving
Border Patrol
agents.
After examining the legislative and judicial history of “border search” authority (particularly the
Almeida-Sanchez
family of decisions) and the policy basis adopted by these authorities, we conclude that after
Almeida-Sanchez
neither agents of the Border Patrol nor of the Customs Service may conduct a search on less than probable cause at a point other than the border or its functional equivalent.
In
Soria
this court distinguished Customs searches from Border Patrol searches during the period prior to June 21, 1973, the effective date of
Almeida-Sanchez.
However, the panel acknowledged that the principal grounds for distinction were the non-retroactive effect assigned to
Almeida-Sanchez
coupled with the statutory and regulatory roles assigned to the Customs and Border Patrol agencies.
Pre-Almeida-Sanchez
searches by Border Patrol agents were governed by statutes, regulations and decisions granting immigration officials (mfettered discretion to search any vehicle for aliens within the 100-mile radius of the border.
United States v. Soria, supra,
519 F.2d at 1062. However, since Customs officials were bound to observe the “reasonable suspicion/border nexus” test even before
Almeida-Sanchez, see id.
at 1062-63,
Soria
simply does not affect today’s analysis, which is directed toward determination of
post-Almeida-Sanchez
customs search law.
Customs searches have a longer history than Border Patrol activities. The First Circuit noted in construing the predecessor of the present Customs search statute,
that
laws conferring the right to search persons and vessels at or near international boundaries have existed since the foundation of the government.
See Lee v. United States,
14 F.2d 400, 404 (1st Cir. 1926),
rev’d,
274 U.S. 559, 47 S.Ct. 246, 71 L.Ed. 1202 (1927); Act of July 31, 1789, ch. 5, 1 Stat. 43 (1789). Immigration searches are of considerably more recent vintage. There was no restriction of immigration at all until 1875, and the authority for Border Patrolmen to search was not codified until 1925.
As the number of customs and immigration violations increased, single officers were empowered to investigate both types of crime. In 1959, this court first decided a case involving one of these two-hatted agents, calling the search a “border search,” and citing both immigration search and customs search cases.
See United States
v.
Ramirez,
263 F.2d 385, 387 (5th Cir. 1959),
citing King v. United States,
258 F.2d 754 (5th Cir. 1958),
cert. denied,
359 U.S. 939, 79 S.Ct. 652, 3 L.Ed.2d 639 (1959) (customs);
Haerr v. United States,
240 F.2d 533 (5th Cir. 1957);
Flores v. United States,
234 F.2d 604 (5th Cir. 1956) (immigration). A year later, in
Barrera v. United States,
276 F.2d 654 (5th Cir. 1960), a search by agents acting under authority of the customs laws alone was upheld on the authority of
Ramirez
and
King; Haerr
was cited in a footnote. Other circuits alternately distinguished Customs and Border Patrol searches and lumped them together as “border searches” governed by similar, if not identical, considerations.
Almeida-Sanchez
required probable cause for searches by roving patrols in the vicinity of the border.
See
413 U.S. at 273, 93 S.Ct. at 2539-40, 37 L.Ed.2d at 602. In
United States v. Ortiz,
422 U.S. 891, 95 S.Ct. 2585, 45 L.Ed.2d 623 (1975), the Court held that searches without warrant or probable cause at traffic checkpoints which were not functional equivalents of the border were constitutionally invalid. In a case decided on the same day,
United States v. Brignoni-Ponce,
422 U.S. 873, 95 S.Ct. 2574, 45 L.Ed.2d 607 (1975), the Court drew the line between authority to stop and right to search more distinctly:
When an officer’s observations lead him reasonably to suspect that a particular vehicle may contain aliens who are illegally in the country, he may stop the car briefly and investigate the circumstances that provoke suspicion. As in
[Terry
v.
Ohio,
392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 899 (1968)], the stop and inquiry must be “reasonably related in scope to the justification for their initiation.”
The officer may question the driver and passengers about their citizenship and immigration status, and he may ask them to explain suspicious circumstances, but any further detention or search must be based on consent or probable cause.
422 U.S. at 881, 95 S.Ct. at 2580, 45 L.Ed.2d at 617. Up to this point, none of the
Almeida-Sanchez
family of cases departed from traditional Fourth Amendment jurisprudence developed in nonborder situations. Rather, they merely applied that jurisprudence in a new context. Searches, wherever conducted, required probable cause. The stopping of persons in vehicles for interrogations and investigations less intrusive than a search could be upheld as reasonable although the officer knew less than enough to give him probable cause to search or arrest.
Then, in
United States v. MartinezFuerte, supra,
the Court' held that a brief investigatory stop could be conducted at a reasonably located checkpoint in the absence of any individualized suspicion. - U.S. at-, 96 S.Ct. at 3084. The basis for the official’s breach of the citizen’s privacy was found in the countervailing public interest expressed in a border control statute, 8 U.S.C. § 1357, which purported to do away with the warrant and probable cause requirements of the Fourth Amendment. But the Court made clear that its decision rested not on the statute but on another traditional Fourth Amendment exception— the regulatory inspection — by citing six cases or opinions acknowledging or suggesting the existence of such an exception.
It
further limited its holding by noting that its balance of the interests of the citizen against those of the government dealt neither with searches nor with private dwellings, but to vehicles required only to stop briefly under largely predefined procedures.
The singular characteristic of the Border Patrol cases is that the Supreme Court has chosen in each instance to strike its own balance of Fourth Amendment “reasonableness,” without regard to the express terms of 8 U.S.C. § 1357. The Court has not relied on the statute or its implementing regulation, despite its language empowering Border Patrol agents to make warrant-less searches and arrests within a reasonable distance of the border and the definition of that distance as 100 air miles. At most, the Court has indicated that the statute identified a potential governmental interest to be balanced against individual rights and affirmed the government’s intent to act to protect that interest.
With this historical perspective, then, three factors persuade us that
AlmeidaSanchez
applies equally to Customs and Border Patrol searches. The first is the common origin of immigration search case law and customs search case law in the
Carroll
dicta relating to international boundaries.
See Carroll v. United States, supra,
267 U.S. at 154, 45 S.Ct. at 285, 69 L.Ed. at 551. As identified there, the interest protected by both statutes is the same: protection of physical or fiscal interests of the United States against introduction of items harmful in themselves or because of their method of entry. In the Customs context, things like narcotics fall into the first category; others, such as tariff items concealed to avoid payment of duty, make up the latter. Border Patrol agents look for “contraband people,” whether they immigrated legally or came in lawfully and overstayed or otherwise became deportable.
The second additional factor, which should be considered in conjunction with the first, is the accompanying governmental interest in judicial economy. In view of the substantial similarities between the government interests to be protected and the consequences to innocent members of the public if the probable cause barrier is lowered, we do not believe the Supreme Court would have created today’s intricate analytical structure for Border Patrol cases only. Third, we note that other circuits have assumed, usually without explicit discussion, the applicability of
Almeida-Sanchez
concepts to searches by Customs officials.
In sum, regardless of the officers’ status, warrantless searches such as Brennan’s must be made on probable cause.
IV.
Since the search did not take place at the functional equivalent of the border and the officers making the search are entitled to no special status under
Almeida-Sanchez,
we must inquirers to the existence of probable cause to search. We conclude that, through a combination of hearsay information from the tip, preflight corroboration of some of the details, and the on-the-scene corroboration of Brennan’s surreptitious
landing at the predicted time and place, such probable cause in fact did exist.
It is settled law that warrantless searches require the same investigative basis in fact or reasonable conjecture as searches under warrant.
See Carroll v. United States,
267 U.S. 132, 156, 45 S.Ct. 280, 286, 69 L.Ed. 543, 552 (1925). Such information may be supplied in whole or in part by an informant.
United States v. Harris,
403 U.S. 573, 91 S.Ct. 2075, 29 L.Ed.2d 822 (1971);
Spinelli v. United States,
393 U.S. 410, 89 S.Ct. 584, 21 L.Ed.2d 637 (1969);
Aguilar v. Texas,
378 U.S. 108, 84 S.Ct. 1509, 12 L.Ed.2d 723 (1964);
Jones v. United States,
362 U.S. 257, 80 S.Ct. 725, 4 L.Ed.2d 697 (1960);
Draper v. United States,
358 U.S. 307, 79 S.Ct. 329, 3 L.Ed.2d 327 (1959). Where insufficient information about the tip and the tipster is available to justify reliance upon it alone, investigating officers may supplement the tip by surveillance of the subject or corroboration of key elements of the tip from relatively objective sources. Although there is no consensus on the type of information required to corroborate an informant’s tip,
it is generally agreed that the better practice is to obtain corroboration of incriminating details.
See Spinelli
v.
United States, supra,
393 U.S. at 414, 89 S.Ct. at 588, 21 L.Ed.2d at 642; Moylan,
Hearsay and Probable Cause
: An Aguilar
and
Spinelli
Primer,
25 Mercer.L.Rev. 741 (1974). However, an accumulation of innocent detail conforming to the original tip has been held to have corroborative value.
See, e. g., United States v. Holliday,
474 F.2d 320 (10th Cir. 1973).
Neither Dufresne nor his tip met the
Aguilar
standards for informant credibility or informational reliability, even if the modified standards for first-time informants are employed.
See United States v. Bell,
457 F.2d 1231 (5th Cir. 1973);
McCreary v. Sigler,
406 F.2d 1264 (8th Cir.),
cert. denied,
395 U.S. 984, 89 S.Ct. 2149, 23 L.Ed.2d 773 (1969). Dufresne stated clearly that his belief Brennan was going to engage in smuggling activity was his own extrapolation from a number of factual details. Objectively, the content of the Brennan-Dufresne telephone conversations is insufficient as a basis for search or seizure. Likewise, there is no sufficient basis in the record for crediting Dufresne’s conclusions on the basis of Dufresne’s reputation alone. Unlike the informant in a typical drug case, Dufresne had no “track record” of prior reliable tips; this case represented his first contact with law enforcement officials and the content of the tip revealed an intimate association with Brennan and his activities.
Aguilar
teaches that (1) the basis of the informant’s knowledge and (2) the information justifying belief in the informant as a person or in the intrinsic reliability of his tip must be present in order to justify a search on the basis of the tip alone.
See
378 U.S. at 114, 84 S.Ct. at 1514, 12 L.Ed.2d at 723. Even though the nature of Dufresne’s employment and his direct contact and confidential relationship with Brennan affords a more reliable basis for assuming his trustworthiness and that of his information than would be present if Dufresne were repeating an underworld rumor or did not know aircraft capabilities, the information presented by and about Dufresne in this record falls short of this standard.
Similarly, the advance investigation conducted by DEA officials failed to corroborate enough of the significant details of Dufresne’s story to comply with the
Spinelli
formula for curing deficient tips. The fact of Brennan’s ownership of a Beagle aircraft, even with the addition of information as to a particular identifying number, is patently insufficient to justify a search; this is precisely the type of innocent detail held to be of insufficient corroborative value in
Spinelli
itself.
See
393 U.S. at 414, 89 S.Ct. at 588, 21 L.Ed.2d at 642. Dufresne’s
story about his and Brennan’s incarceration in Colombia could have been more valuable, but in view of the ultimate dismissal of the Colombian charge, we find it insufficiently probative of Brennan’s future plans to smuggle drugs into the United States to hold that it supplied the informational link missing in the tip. Further, the agents’ failure or inability to verify some of the more damaging details reported by Dufresne — the installation of auxiliary fuel tanks, Brennan’s precarious financial condition or his indirect attempt to acquire a loran, for example — over a relatively lengthy period preceding Brennan’s anticipated date of flight has, if anything, a slightly erosive effect on the believability of Dufresne’s account.
Of course, the inability to amass corroborating detail had two effects. One effect was to render it highly unlikely that a valid warrant could have been obtained in advance of May 18. A second and reciprocal effect was to require the additional investigation of Brennan’s activities that led the DEA and Customs officials to be on the scene at the Melbourne airport on the morning of May 18. At the point at which the law enforcement officials detected the Beagle aircraft proceeding down the taxiway in the dark with its lights off, at a time almost exactly that predicted by Dufresne in his estimate for the time required for a smuggling flight, the quantum-of-knowledge ring closed around Brennan in the manner approved by the Supreme Court in
Draper
v.
United States,
358 U.S. 307,79 S.Ct. 329, 3 L.Ed.2d 327 (1959). Through self-corroboration, equivocal information ripened into probable cause on the scene.
In cases where searches are made without warrants, the Supreme Court has decreed that the existence of probable cause must be accompanied by circumstances rendering the warrant procedure impracticable.
Warden v. Hayden,
388 U.S. 294, 87 S.Ct. 1642, 18 L.Ed.2d 782 (1967). We believe that those exigent circumstances were present here when Brennan landed at the airport in his Beagle aircraft. Because of its mobility the plane could have been
stopped and searched any time after probable cause was generated,
i. e.,
as soon as it was identified on the taxiway. However, an attempt by the agents on the scene to have surrounded the plane on the taxiway might have resulted in alerting Brennan or in injury to the officers or others present at the airport. Accordingly, we do not believe that it was a violation of Brennan’s Fourth Amendment rights to allow the chances of escape or armed confrontation with the officers to decrease by permitting him to proceed to his hangar. Further, in a very real sense, this case is analogous to
Chambers v. Maroney,
399 U.S. 42, 90 S.Ct. 1975, 26 L.Ed.2d 419 (1970);
Texas v. White,
423 U.S. 67, 96 S.Ct. 304, 46 L.Ed.2d 209 (1975), and
Warden v. Hayden, supra.
Without holding that an airplane is the legal equivalent of an automobile for purposes of search and seizure, we note that the slightly greater difficulty of getting away from the scene in an airplane occasioned by the need to achieve takeoff speed is offset by the 360-degree range of airborne escape routes. As in
Warden v. Hayden,
and in contradistinction to
Coolidge v. New Hampshire,
403 U.S. 443, 91 S.Ct. 2022, 29 L.Ed.2d 554 (1971), the officers followed Brennan into the place of search with relatively little elapsed time.
See also United States v.
Santana, - U.S.-, 96 S.Ct. 2406, 49 L.Ed.2d 300 (1976). We note further that both the car and the panel truck outside the hangar were registered to Brennan. Since one person cannot drive two cars at once, and since it is unlikely that one person would conduct an entire smuggling operation involving 1600 pounds of marijuana alone, the record supports the reasonableness of an inference by the agents that confederates might be present, with an attendant danger of destruction or dispersion of the evidence if the warrant procedure had been followed.
See Guzman v. Estelle,
493 F.2d 532, 536-38 (5th Cir. 1974);
United States v. Scott,
520 F.2d 697 (9th Cir. 1975), cert.
denied,
423 U.S. 1056, 96 S.Ct. 788, 46 L.Ed.2d 645 (1976);

102 (6th Cir. 1974),
cert. denied,
421 U.S. 975, 95 S.Ct. 1974, 44 L.Ed.2d 466. Accordingly, we hold that on the facts presented by this case, both probable cause and exigent circumstances were presented to the law enforcement officers at the Melbourne Regional Airport and that the search of Brennan’s plane was justified under traditional Fourth Amendment standards. Therefore the motion to suppress was properly denied and the convictions are
AFFIRMED.
