I remember a woman telling me about what she thought was the biggest faux pas she'd ever made. A friend and friend's new fiance were attending a party she was having. Among small talk it came out that the fiance was a pilot. "Oh, really?" quoth the hostess "I'm a white knuckle flier myself, expect to crash in the woods anytime and end up eating my seatmate or something."
Dead silence followed, conversation languished, the couple soon left. After which another person at the party, in somewhat shocked tones, said "Don't you know who he is?" Turns out he was a pilot who crashed up North years ago and was believed to have eaten some flesh off the nurse he was flying with, who had died in the crash.
