Yes. I just saw someone post about it on Facebook that I volunteered with last year. He was there, but not on the flight. I know the pilot and one other crew member didn't make it. I met the pilot last year, actually helped change the tires on that plane, and took my whole family up in it too.
I wouldn't trust anyone to fly that more than Mac, he had more hours flying a B-17 than anyone on Earth (if I had to guess more than anyone, EVER). The pilots in the other planes rotated (the pilots are all volunteers), but Mac traveled with them year round and was ALWAYS the pilot in the B-17. He was an ornery guy, and things had to be done his way for sure, BUT he was a good teacher too. Hearing him and the co-pilot banter while I was on the plane (with headset on) would make you laugh. Especially because I could hear them talking and the co-pilot not doing what Mac wanted (this was on a landing), Mac said "you really gotta wrestle this bitch" (as the tail was wagging back and forth) before he took over and brought the tail down smooth.
I won't say I was close to him, but he reminded me a lot of my dad (and I have said that BEFORE the crash). Had bad knees so he kind of walked like my dad, but he was ornery too, BUT was a good person behind the old codger facade.
