If the problem was your radio , wouldn ' t you follow your basic NORDO procedure ? Fly 500 ' above pattern , orbit the field until a light gun signal is received . In the case of being on the ground , roll up to and hold short of a taxiway with all your lights on and in clear view of the tower . There ' s nothing to suggest the helicopters didn ' t suspect their own radios at first , but determined otherwise . There ' s a lot of facts and circumstances here that suggest to me that the pilots made the best possible decision . However , there is not a lot of detail in general so it will be interesting to see what comes out . edit typo <| sep |> I saw an article in the same vein posted here a while ago dismissed as nothing serious etc , but is there some truth to this one ? Could Egyptian troops join the fight ?
