Wow that is a real eye opener. Anyone know if there is any benefit other than cost saving. Particularly worrying would be Gol flying long distances over Brazil out of thirty minutes range of an airfield or All Nippon that had a couple of aircraft doing long range all business class services. That is the sort of information that would help me decide who not to fly with. Unlikely as the loss of all generators might be, the recent russian incident shows it is possible.
