It’s all up to God, ultimately.
Take note that the Messerschmitt Me-262 jet fighter had all of the characteristics that most jet airliners have taken on, too, down to the swept-wing design.
I met General Robert L. Scott at a historical society in South Georgia.
Although he was pushing 90 he was sharp as a tack and really charismatic. I talked to him a little while and he told me about his time in Panama, flying a P-39 which he used to shoot sharks. He liked the P-39.
He said the AVG never fought against Zeroes and technicllly Scott was not a member tho Chennault did let him fly with them. After it became the 14th Air Force, most of the original AVG left. They did keep a few.
I do remember Scott saying that the last model of the P-40 was pretty hot. It would do well over 400. Scott ended up flying P-51s when they became available.
