Mostly because of speed I guess. Going too fast when I try to set wheels down. I have been getting better tonight. I almost landed a f-15c that nose and part of one wing was shot off. I made it alive, but landing gear collapsed and started a fire, but hey I got out. I just landed my a-10c at night and landed a mig29 during the day. I just think it is funny how the first time and since I can land on a carrier but was crashing on the runway on land.
