Two bugs;
First; looking at a mission from the outside I did see 3 planes stop in midair over an airfield during a strafing attack they did never move again!
Second; if you land last during a mission all the planes that land before you and disappear from the game before you land are counted has destroyed! Strange is it not.
It is a nice game.
