> A large number of them have died.

Paul Preuss (October 3, 1913) died during an attempt to make the first ascent of the North Ridge of the Mandlkogel free solo, fell a thousand feet

Man. According to Wolfram Alpha[1] it'd take 7.9 seconds to fall 1000 feet, with a final velocity of 170mph (77 m/s).

I thought that terminal velocity for a human on Earth was about 120 miles/h. Seems like Wolfram doesn't take that into account.

Just makes the horrifying fall even longer!

170 mph assumes no air resistance

Yup, I understand that. My point was that that's not a very accurate assumption in the vicinity of El Capitan :)
