Dh was really thinking of AK a while ago but I put my foot down. I’m too old.... I don’t know what the Alaskan triangle is.
Something like the Bermuda Triangle, at least as far as this link indicates:

Not just planes that go missing there, either. I remember reading in one of Frank Edwards' books ("Stranger Than Science", I think?) about an entire village of inuits that was there when trappers passed through on their routes, and had completely vanished when the trappers returned not long afterward. If I remember correctly, there was a skin spot of stew still cooking over a small fire, but not a soul was present in the village. No one ever learned what had happened to them.
