I have to admit I don't understand this "less realistic" perception. To me, it's less realistic to hit ".ef" on the runway and be whisked back to the tower, where I have a choice of any brand-new plane in AH, click fly and be rolling down the runway in seconds.
OTOH it seems more realistic to me that if I bring back a bent or broken bird, I have to sit around and wait while the mechanics work on it. The fact that it takes much less time than it would in real life doesn't bother me, many things are faster in AH than they would be in real life.
Of course the beautiful thing about this idea is those who like it can take advantage of it, while those who don't can just ignore the feature....
And for the Navy flyers, I'd like to see an operable deck elevator feature put in on the CVs. I think the CVs are modelled with below deck spaces, aren't they? Just land, taxi to the elevator pad, hit a key, and be lowered into the below deck hangar, where the same repair routine and sound effects could take place.
