Rescue

Where a climber carrying humans becomes stuck and evacution is the only possible remedy then jumping from the climber is feasible as was shown by Felix Baumgartner an Austrian skydiver, daredevil and BASE jumper who set the world record for skydiving of an estimated 39 kilometres (24 mi), reaching an estimated speed of 1,342 kilometres per hour (834 mph), or Mach 1.24, on 14 October 2012. For such an escape the escapee would need a pressurised suit and air supply and some experience of freefall to attempt this successfully. Felix Baumgartner record jump does demonstate that such an escape would be a feasible if risky option. Such an escape would require a jumper to jump clear of the ribbon. Alternative escape method could utilise abseiling the cable which could be used to slow the descent. The most likely rescue would be to send up a second climber. This would require the transfer of a human cargo and any transfer above 13 km (c. 8 mi) would require either airlock facilities or a pressured suit.
