Bo Darden, 69, has been flying the hills of Western Alaska since he moved to Dillingham in 1971. Speaking about what might have caused the Aug. 9 crash that killed five, Darden said "Who knows? I have no idea. You'll probably never know, either. The Feds will make an educated guess, but that's about it."
