On Saturday march 11, 1967, a little single engine cesna set off, from Portland bound for San Francisco, on what was supposed to be a relatively short and routine flight. However, several hours into their flight, they encountered a freak storm that would cause the plane to crash on a literal mountainside. Miraculously, all the occupants would survive the initial crash, but what they would go on the endure in the next few weeks would be one of the most prolonged and grueling ordeals in the history of the region. So much so that it would forever change the course of aviation. This is their horrifying story, and as always, viewer discretion is advised.
