From: Crystal Palace, London.
In total 364,514 operational sorties were flown, 1,030,500 tons of bombs were dropped and 8,325 aircraft lost in action.
Interesting, that's about 2.3% overall, so if we assume that a maximum acceptable loss rate (in the short term) to be about 5%, there have to be some ops when no losses are taken. As a general rule of thumb this could be quite manageable in the game, so maybe the simulation is better balanced than we sometimes think it is.
