So how did Davis die?
I know it's possible to die from a high fall into water.
Heck, people do it all the time in that very city when jumping from the Golden Gate Bridge.
But what bothered me even as a kid when I first saw it is that Davis's stunt double obviously made the actual jump himself, meaning it had to have been safe enough for a stuntman.
So why would it kill Davis, who is implied to be in peak condition and an ex-soldier?
