De-Fuelling
If I had to guess the fire crews are standing by with all their equipment "locked and loaded." The fuelling company is certainly handling the actual transfer. Note that de-fuelling in and of itself is nothing special. Just flip a switch on the tanker truck. Happens often enough when too much fuel was transfered to a plane.
But... when working under a collapsed and likely unstable wing, in the dirt (or mud), things get dicey. I never fuelled a 747-200-- it is an ancient model used only for freight-- but the more modern 747s have two fuelling stations, one under each wing. One non-trivial point is, how far off the ground are the stations? Ladders, lift trucks, &c., are designed for certain heights. With these wings so close to the ground that indicates a lot of muscle will be needed. Plus the hoses are not very long since they are designed to reach from a truck parked under the wing, to a nearby station.
Rule #1 for a refueller: The hose always wins. Check out the cats fuelling your next flight... bulging muscles are a job requirement.
Presumably all the "hot parts" were allowed to cool afore starting fuel work. But hot parts on a gas turbine are very @#$%ing hot. Takes a long time for them to get touchable, as it were.
