Plaintiffs, CIVIL ACTION NO.: 4:19-cv-169

v.

THE UNITED STATES OF AMERICA; AVIATION DEVELOPMENT GROUP, LLC; and THOMAS HUFF,

Defendants.

O RDER This case emerges out of a tragic airplane crash that killed William Byron Cocke and Catherine Crichton Cocke (“Decedents”). (See generally doc. 387.) Plaintiffs are: John Hartwell Cocke, as Executor of Decedents’ estates; William Ruffin Coleman Cocke in his individual capacity; William Marston Becker, as Conservator of Decedents’ minor children; and John Hartwell Cocke and Viginia Frances Cocke, as Guardians of Decedents’ minor children. (Id. at pp. 3–4.) Defendants are: the United States of America (hereinafter, the “Government”), being sued under the Federal Tort Claims Act (“FTCA”), 28 U.S.C. §2671, et seq.; Aviation Development Group, LLC (“ADG”), a Georgia LLC; and Thomas Huff, the sole member of ADG. (Id. at pp. 4–7.) The Government has also filed a crossclaim against Defendants ADG and Huff (“the Cross Defendants”). (Doc. 92.) Before the Court is the Government’s partial Motion to Dismiss, in which it argues that certain claims Plaintiffs have raised are barred by sovereign

immunity and that this Court consequently lacks subject matter jurisdiction over those claims. (Doc. 428.) Plaintiffs and the Cross Defendants have each filed a Response. (Docs. 461, 481.) The Government has filed a Reply to Plaintiffs’ Response, (doc. 515), and the Cross Defendants’ Response, (doc. 508).1 After carefully considering the parties’ arguments, the Court GRANTS the Government’s Motion to Dismiss. (Doc. 428.) BACKGROUND Plaintiffs allege the following in their Fourth Amended Complaint. (Doc. 387.) On August 28, 2017, Decedents were killed in a plane crash resulting from an in-flight engine failure. (Id. at p. 9.) The aircraft departed from the Savannah/Hilton Head International Airport for a flight towards Atlanta, Georgia. (Id. at p. 11.) Approximately five minutes after takeoff, the pilot

declared an emergency and informed the Savannah Air Traffic Control Tower (“SAV ATCT”) of the engine failure. (Id.) The air traffic controller on duty (“SAV ATC”) provided the pilot with two options for landing: either return to the Savannah airport or attempt to glide towards an airport

1 The Government notes that the Cross Defendants’ Response was filed after the Court’s May 23, 2025, deadline for responding to civil motions other than motions for summary judgment, and instead was filed on the June 9, 2025, deadline for responding to motions for summary judgment. (Doc. 508, p. 1.) The Government urges the Court to disregard the Cross Defendants’ Response under Local Rule 7.5, which states that a failure to timely respond to a motion “shall indicate” that the motion is unopposed. (Id.) L.R. 7.5 does not mandate that untimely responses be disregarded and instead grants the Court discretion over whether to consider a late response. Odom v. Coastal States Auto. Grp. Mgmt., LLC, No. 4:20-cv-264, 2022 WL 3586693, at *5 (S.D. Ga. Aug. 22, 2022). While the Cross Defendants’ tardiness is objectionable, their response was not egregiously tardy and addresses the substantive arguments raised by the Government in its Motion. As such, the Court declines to disregard the Cross Defendants’ Response. See id. (declining to deem a motion unopposed where a response was filed thirteen days after the deadline). in Statesboro, Georgia. (Id. at p. 12.) The pilot determined that he could not make it to the Savannah Airport and turned the aircraft towards Statesboro, resulting in a significant loss of energy and altitude that substantially reduced the aircraft’s glide range. (Id. at pp. 12–13.) As the aircraft continued to lose altitude, the pilot asked SAV ATC for the distance to the Statesboro

airport. (Id. at p. 13.) After some initial confusion, SAV ATC informed the pilot that Statesboro was 20 miles away. (Id.) Faced with a failing engine and losing both energy and altitude, the pilot determined that the aircraft likely could not make it to Statesboro. (Id.) SAV ATC then provided the pilot with a third option for landing—the Cypress Lakes Airport in Bloomingdale, Georgia. (Id.) Cypress Lakes was much closer to the aircraft’s position when the emergency was first declared and was visible on the SAV ATC’s Radar Video Map (“RVM”) but was not initially presented as an option to the pilot. (Id.) The pilot by this point had no choice but to turn the aircraft towards Cypress Lakes, losing substantial energy and altitude in the process. (Id. at p. 14.) Attempting to reach Cypress Lakes proved too much for the failing aircraft, and the plane crashed in a wooded swamp area en route to Cypress Lakes. (Id. at pp. 14–

15.) Decedents died in the crash. (Id. at p. 15.) Another airport, Briggs Field, was also available and was much closer to the aircraft’s initial position during the emergency than the Statesboro airport. (Id. at p. 14.) However, the airport was not depicted on SAV ATC’s RVM and was never presented to the pilot as an option for landing. (Id.; doc. 461-12, p. 4.) The failure to depict Briggs Field was allegedly due to SAV ATCT’s ignorance of the airport’s existence. (Doc. 461-12, p. 5.) John Hall, the manager for the SAV ATCT at the time (the “SAV ATM”), has stated that the facility was unaware of Briggs Field before the crash. (Doc. 461-13, p. 3.) As facility manager, SAV ATM was responsible for the data displayed on the RVM. (See doc. 428-13, p. 3.) Others at SAV ATCT have also stated that the facility did not know of Briggs Field before the crash. (Doc. 461-14, p. 5.) Plaintiffs brought this wrongful death and survival action seeking damages arising from the airplane crash. (Doc. 387, p 2.) Plaintiffs allege that the failure to list Briggs Field on the

RVM constitutes negligence by the Government. (Id. at p. 20.) Allegations pertinent to the present Motion include that the Government “violated air traffic control policies, procedures, rules and/or regulations by providing . . . controllers with an RVM . . . that was inaccurate” and that the RVM that was provided “failed to list certain airports that were safe and appropriate for the subject aircraft to land.” (Id.) The Government moves to dismiss all claims relating to the design and content of SAV ATCT’s RVM pursuant to Rules 12(b)(1) and 12(h)(3) of the Federal Rules of Civil Procedure. (Doc 428, p. 1.) The Government claims that it has not waived its sovereign immunity for such claims under the FTCA and that this Court thus lacks subject matter jurisdiction over them. (Id.) Specifically, the Government argues that these claims are barred by the FTCA’s discretionary

function exception. (Id. at pp. 8–19.) This constitutes a factual attack on the Court’s subject matter jurisdiction. See OSI, Inc. v. United States, 285 F.3d 947, 951 (11th Cir. 2002) (citations omitted).
