Last night after we passed over the hour mark and 105 was pretty much flat and the fight was done, myself and 3 squaddies rolled into A1 to land and we all stopped, I turned off my engine and got a ditch? Now I know I am gonna get the "Were you on the runway" question. Yes I was on the runway, yes I was stopped (you can't end flight anyway while rolling), and yes I am sure of the two facts above. Why did this happen and what does it do as far as aircraft lost for that frame?
