You end up thinking the presumed short set fire to some other component in the ELT and that fire then spread to set the battery off . . except very few professional grade electronic components burn for long or that well in a sealed container. . .
Jetstream67, I'm with you on that. That's why I wondered if the beacon were a red herring. We need pictures and more information! How does the NTSB and other investigators expect PPRUNE to help them solve the problem, if they don't give us the information! It's almost as if, they don't care if we help or not! BTW: If you European's had used Aluminum, instead of Aluminium, on your aeroplanes, you wouldn't have needed to resort to composites on Airbus! ...Kidding, of course!
