I also think it is a good idea

since I also brought up a simular suggestion not too long ago. But, I think what SpitLead says makes sense too.
I think we could use a 'cumulative damage system' to go with hangar repairs. Currently, I think AH damage model is sort of.. well.. arbitrary in depicting the way a plane is damaged. Shots fired are either hit or miss, no damage or damage, and the results are always either 'nuthin' doing' or 'total destruction'.
The plane is actually a very big target(quite amazes me to see pictures of a 'small plane' like F6F-5 with like, 5 guys sitting on the wing alone..

), and though numerous shots are fired the projectiles itself are also very small compared to an airplane.
I mean, if many shots are landed and it has some deep effect on the wing, it doesn't necessarily mean a wing goes off. For instance, aileron damage might be extensive from mild disturbance in the hydraulics system to actual total destruction of the aileron.
AH depicts damage as either 'no damage' or 'total destruction'. I say we put in something between - 'very light damage', 'light damage', 'heavy damage'. Then, in cases of 'very light damage' or 'light damage', we might get to fix something in the hangars
