You must have missed the "to share or not to share" thread from a month or so ago. The consensus—as I understood it—was that if you have to ask, you're not worthy of knowing the answer. So I think you'll find yourself out of luck here with anyone who actually knows.
I've never seen the crash, but I think I've read that it's west of the summit. There is a herd path over that direction; I accidentally took it last September. It's a right turn a few dozen yards (that's a guess) from the top along the path to Donaldson. Does the path lead to the crash site? I don't know.
As I said, I didn't notice any plane crash, but I wasn't looking for it; I was looking for my partner, who had taken the correct path to the summit, and I quickly retreated when I heard her call for me.
