I worked with a guy in the '70s and early '80s who was a B-24 nose gunner on some of the Poesti raids. I'm not sure exactly when, but it was probably later in the war, as he told me a story about a squadron(?) of 24s (not his) that suffered enormous losses to Me-262s. I don't remember the exact numbers he recited, but it was something like 16 out of 21 bombers lost. The crews greatly feared running into the jets. He said he never saw a fighter on any of his missions. Luck of the draw, I suppose.
He retired a good while back. I assume he's dead now. He was a good man and a good toolmaker. He taught me a great deal when I was an apprentice. His name was Bill Bond.
