Virtually no B17 or B24 "bombing" missions were flown above 25,000 feet. It was hard on the engines and bombing accuracy suffered and They were too heavily laden with fuel, ords, and the weapons created too much drag. The max ceiling for a B17 was 36,500 feet'BOEING AIRCRAFT STAT. The USAAF stats are 32,500 feet alt for a 50,000 pound B17 take off weight-under 22,000 for 1 weighing 65,000 take off weight- and under 26,000 for 1 weighing take off weight 60,000, but that is for one weighing 50,000 pounds take off weight. The 21st Bomber command tried using b29s at 30,000 but They couldn't be sure of hitting anything with a bomb except for the ground and it was very hard on the engines. Other planes like the Mossy16 had good alt performance, but didn't have the ability to accurately bomb from very High alt. A modification in modeling would make it more realistic,but the strato sortie bufftards would not like It. I'm sure They don't like the new All Seeing Eye either. But a layer of clouds at 26-27k covering the strats would be a step in the fairer direction. Have a blast. I don't really mind the fantasy bombing alts when a spit14 is available. Mjug My second choice. Anyway , Have a blast.
