[quote="HB-JVR"]Je sais plus qui l'as écrit mais il a dit que le siège du F-404 à éjection vers le bas n'avait était gardé que sur les protos. Il y aurait pas eu les premiers exemplaires de services aussi ?[/quote]

[quote]The first F-104As were fitted with Lockheed-designed downward-firing ejector seats. Lockheed engineers had feared that upward-firing ejections would not be safe at the speeds at which the F-104 would be flying, the seat supposedly being unable to clear the tall vertical tail at such high speeds. Consequently, they opted for a downward-firing ejection system. The system was the first fully-automatic downward-firing ejection system ever employed in a production fighter. When the pilot initiated the ejection sequence by pulling the ejection ring, an automatic sequence of events was initiated. First, the cockpit depressurized and the flight control stick retracted. The parachute shoulder harness then tightened and the pilot's feet were pulled together and clamped into place. The escape hatch was then blown off the bottom of the aircraft and the seat fired, ejecting the pilot out the bottom of the airplane. This system proved to be unsafe in service, since it was useless for emergencies that occurred during landings, takeoffs, or anywhere near the ground. In order to eject safely at low altitudes, the pilot would first have to roll his aircraft inverted and then eject upward out of the bottom of the plane. This was of course not always feasible, and the famous test pilot Iven C. Kincheloe was among 21 F-104 aircrew to be killed by the deficiencies in this escape system. Consequently, the downward ejection system was quite unpopular with F-104A pilots and was replaced in the field by the more conventional Lockheed C-2 upward-firing ejector seat. [/quote]

Voilà...voilà...donc "F-104A only" et encore que les premiers produits.
Nan, mais çà fait plaisir de vous mettre des liens les gars hein!!
