I hope they model the burn time properly, the historically accurate fuel load allowed for burn times of 8-10 minutes, according to the National Air & Space Museum and a bunch of other places I looked.
In regards to those suggesting that HTC model reliabillity for these, I suggest that fair being fair, we take it to the next logical step:
1. The Jumo engines in the Me-262 and Ar-234 should explode on fast throttling and should also randomly fail.
2. All late model Luftwaffe planes should have engine performance fluctuate between 80-100% to simulate the poor quality of fuel that they were forced to use in the last years of the war.
3. Bomber formations should be 20 planes instead of 3, because there were almost always more then 3 planes in a mission.
4. Radar (specifically dot-dar) should be removed and replaced with a scope that indicates signal return levels in a circle. Sure, you wouldn't know if the spike was because of a plane or a mountain, but don't worry, it would be historically accurate. Oh, and it wouldn't be available in-flight.
and so on. After all, we want this reallistic, right?
