Scavenging a crashed 777: for a book

[MAC 40612]

I've just found this thread

Oxygen cylinders approximately 13-16 [depending on seating configuration] all located in the rear freight bay right hand side wall. One crew oxygen cylinder located in the left hand crawl-way under the floor at the front on the aircraft.

With regards to the transponders and such like. Only the selector panels for these and communications are in the flight deck. All the actual transmitters/transceivers are located remotely below the floor in the MEC [MainElectronics Centre] so all the wiring would need to be intact between the head end [selector units] and the actual transceivers for them to work

With regards to making stretchers. Most Boeing 777s I've worked on have crew rest areas for flight crew and sometimes also cabin crew located up a staircase in the upper part of the fuselage. The flight crew rest area tends to have at least two beds, while the cabin crew rest area has about eight beds. All of which could be re-purposed into stretchers.

Economy [Coach] class seat squabs [the seat base] are all normally easily removable, they are only held down to the seat with velcro fastening. Only seats in Business/First tend to have seat cushions that are harder to remove.

Modern aircraft beverage makers only have very small boilers [typically enough to make a couple of pots of coffee/tea] before they need to refill/reboil.
