Air France Flight 1611 (AF1611), operated by a Sud Aviation SE-210 Caravelle III, was en route from Ajaccio, Corsica, to Nice, France, on 11 September 1968 when it tragically plunged into the Mediterranean Sea near Nice, resulting in the loss of all 95 passengers and crew on board. The official investigation determined the accident was unsurvivable. This incident remains the deadliest aviation disaster to have occurred over the Mediterranean.

The investigation identified a fire of undetermined origin in the rear lavatory as the most likely cause. Initial theories proposing a surface-to-air missile strike—due to the proximity of a military firing range—were formally dismissed. Nevertheless, families of those lost continue to advocate for the release of classified documents, a stance supported by President Emmanuel Macron in 2019.

Final report

The French Ministry of Transport's inquiry commission published its conclusive findings in December 1972. The report attributed the catastrophe to a fire ignited in the passenger lavatory, potentially caused by either a malfunctioning water heater or a cigarette improperly discarded into a waste bin. It dismissed missile strike hypotheses based on factors including the aircraft’s duration of flight post-fire alert, examination of debris, precedence of similar Caravelle fires, and confirmation from France’s defence ministry that no missile-equipped vessels were present nearby.

Among those who perished was French general René Cogny.

Missile theory

On 10 May 2011, Michel Laty, formerly an army typist, asserted during an interview on French TV channel TF1 that the crash resulted from a missile accidentally launched by the French military during weapons testing.

A The Guardian article from 2019 highlighted that following the disaster, certain documents and photographs disappeared. The logbook entry for 11 September from the French Navy missile frigate Le Suffren, which was operating nearby at that time, was reportedly removed. The aircraft’s black box was said to have sustained damage rendering flight AF1611’s data unreadable, although recordings from prior flights remained intact. Additionally, wreckage was seized by military authorities. In 2011, gendarmes initiated an investigation, with an examining magistrate expressing near certainty that a missile had struck the aircraft.

In 2019, President Emmanuel Macron communicated with a victim’s relatives expressing optimism regarding declassification of pertinent files. He instructed Armed Forces Minister Florence Parly to request that the Committee on National Defence pursue the release of military archives connected to this event.
