I watched an El Cap Rescue in the 90's. They had to long line the climber out of there. It looked like a hell of a ride. A helicopter rescue on that face often requires that the chopper comes in very close to the wall. Blades are often coming within something like 6 feet of the wall. So they obviously don't want to be there long. It's swoop in connect the line to the climber, cut away his anchor gear and yank him off the wall. The dude being rescued looked like he was pitching a fit just before he found himself swinging out into 3,000 vertical feet of space.
Those helicopter rescue guys are just amazing.
