MYT DC-10 Engine Start up
Just something i observed at MAN today, MYT DC-10, G-TDTW, was at stand 22 being prepared for its flight. Alsorts of unusual noises were coming out of what appeared to be the tail engine, ending in what I can best describe as a 'pop' noise and a bit of exhaust fumes.
Then just before it was about to be pushed back, a big blue servisair truck pulls up which has some sort of generator on the back and two flexible pipes leading from the truck were placed into the forward part of the fuselage.
The generator then started and the noise was tremendous for about 5 minutes with a huge amount of black fumes coming out of the generator. The aircraft then pushed back and started the other two engines I just wondered what was actually going on here never seen it before, not really comforting for a passenger on board.
My only thought that it was compressed air in order to start the tail engine (as that seemed to be the result of the whole process). But I really don't know at all, any info guys?
