Nighttime.
Over MEM at FL330.
The fat fingered Flight Engineer managed to trip off all three engine driven generators.
Unable to reset.
APU unserviceable.
Landed at MEM on ships battery power.
All three GCU's reset, engines started, all was well.
F/E told to keep his hands OFF the GB's thank you very much.
Type acft...L1011-1
A big thank you to FedEx, who provided ground power and the biggest huffer I've ever seen, for engine starting...a turbine unit, which I'm sure could have started all three engines at once.
When asked...how much do we owe you?...the reply was, nothing at all, happy to be of service.
Nice folks in MEM, for sure.
