Good afternoon, ..thanks.. gee the B737 electric pages are really comprehensive. Last year ,as pax in a B734 I got an experience of having to get off the a/c when all electricity suddenly gone in that night . It happened in only a couple of seconds after pushback started. The plane was towed back to gate, door re-opened and with the help of F/A flashlight all pax alighted . From a good distance I saw pool of liquid formed in the tarmac apparently made by dripping jetfuel aft the wing. Burst fuel line to APU ?, surely had stopped the only generator running. If my assumption was right , should the battery powered static inverter automatically replace the lost AC power?. I remember very well, of how the F/A could not instruct anything to pax through the P/A.
Thanks again,
