Whatever happened rendered the radios and transponder, as well as the crew O2 inop. Apparently it did not affect the A/P.
" Apparently it did not affect the A/P."
and there to my mind is the problem with the theory of the crew O2 bottle exploding and causing the accident - you've got to come up with a way of explaining how a fire/explosion can disable significant comms components in the MEC but seemingly leave the A/P and all it's associated systems intact enough to "fly" the aircraft, according to some theories for several hours. Credible? One for our engineering colleagues to answer I think.
And while I'm at it if anyone has to be informed yet again that on the 777 you do not turn the transponder to standby to change the code, you just punch in the code.....and touching the transponder at all, even a teeny bit, is
not part of the Boeing Rapid Descent procedure I'll..........cry
