Had the same thing. Must be the Ghost Squadron ...

Another thing I noticed already yesterday and again today.

These small single plane T-shaped hangars are a deadly trap to any plane spawning there. One notorious airfield where this happens is Coquincelle (I think that was the name, it is right West of Calais).

When one turns on one's engine even with as low as power as possible and standing on the brakes the plane will turn by itself and bamboom explosion.

Following solution should work:
place an object (static should work I think) into each of the T-shaped hangars and the game should automatically delete this spawnpoint. Players then should spawn at another spawn point. There should be some outside a hangar.

I also think there is still one red flak left on the French coast. Ok. The Brits left it perhaps behind after their evacuation from Dunkirk but I doubt they left the crew there too ...
