And do you really think that pilots were ordered to go into situations where they had a small chance of survival? The US 8th AF stopped deep penetration missions when the casualties rose to 10%. The Luftwaffe switched to night bombing when their casualties became unsustainable. There were 36000 or so Bf-109s built from 1938 to 1945. I'll bet we lost more than that last month, though I haven't checked.
Yoiur completely wrong Hubert - Read the Book Fighter Boys about the Battle of Brittian. Those guys constantly flew into unsurmountable odds and many lost their lives. They did not fly safe and most of the time flew strait into the German hordes.
No they did not fly to die, but none of them thought about dying while they were fighting. Many recount their first combat expieriance. As soon as they realized the neat puffy trails were tracers being shot at them they went throught a few split seconds of numbing debilitating fear replaced by shear survival instinct and none of the accounts started with running. Most of them fought it out to the death.
Nopoop is right. They didn't pick and choose the safests fights etc, they were told to intercept, interdict, attack and they did not thinking of anyhting else except those orders.
Now on the other hand if you take the French maybe they did. During the battle for France and the witdraw at Dunkirk, the brits had mentioned that the French Air forces didn't even up half the time and stayed on the ground.
