I'm trying to fnd out what the longest single pitch rappell ever completed is. I found a reference that was several years old for a 550Meter, which is only about 1800 ft. I'm planning a trip which will include a rappell of aprox 2500ft, and was suprised not to find reference to anything higher. This is not that difficult of a rappell, and I would have expected this to be a record that many people would be interested in breaking. Any reference you could provide would be appreciated.
