Yes, ditto for the Gimli Glider, the Air Canada 767 that ran out of fuel at altitude and was brought down safely on a drag strip (former runway) in Gimli, Manitoba: http://www.frontier.net/~wadenelson/successstories/gimli.html Air Canada had just switched to SI for fuel, and when the fuel gauge became U/S, the copilot took a dipstick measurement and used the wrong calculation.
