UAL 854 on April 13, 2004. My younger brother Brian Witcher was Captain. ALPA Superior Airman awarded to the crew. Root cause was corrosion at the AC/DC grounding bracket which caused a nearly continuous loss of electrical power. This was an ETOPS aircraft (B767-300) and if not for the emergency landing at BOG after 42 minutes it would have been a disaster. There is a good read on this in the October 2005 ALPA magazine. What I never quite understood was the inability to select the HMG or RAT on the 767 although due to the nature of the failure (total loss of the grounding of current) I believe it would not have made any difference. I myself flew for EAL from 1979 to the strike in 1989 on the 727, A-300 and the DC-9. Not pertinent to this topic but I just retired this month from a single corporate job I held from 1990. Flew the CL60, GV and G550.
