I once accompanied some company freight in an An12. As we were taxying out for t/o the "loadmaster" came over and asked how much the cargo weighed!!!
At the en-route nightstop on a dark cargo ramp deep in Redland the crew just walked off the aircraft and left us in the cabin, saying nothing, no liason about hotac, transport, immigration, not a word, not even goodbye! We didn't even know they'd gone for 15 minutes or so.
They told us the aircraft went back to Russia for maintanance "once a year".
On arrival our destination was fogged out so they diverted to adifferent country and tried to unload us there. We had to be very insistent that they took us where we needed to go, not just somewhere "nearby" (200 miles)
Different book indeed!
