Remember this?
February 20, 2008: Three of four electrical systems on a Qantas Boeing 747 approaching Bangkok from London were lost due to water leakage in the forward galley. Cabin crew used blankets to mop up the leak, and the jumbo was forced to land on battery back-up. Now do please tell me this is a different aircraft. This is an area known for corrosion issues...thats where I'd be looking first. Best, Sicknote
