Any guesses what happened next....?
Just a guess, having never done this but after 30 secs or so an engine in flight will have spooled down to windmill, but I'm assuming these guys were on the ground (hopefully) so the engines would have spooled way down to zilch. The generators would have cut out as well and supossedly you would be on battery power if they hadn't disabled that as well.

Now if the ignition was still on and they energized the spray (or dribble) function then the fuel would simply dribble to the tailpipe and out on the ground. But if they still had a fair amount of air left in the compressor than the fuel would ignite in the combustor and quickly spread to the fuel dribbling into the tailpipe with a big swoosh, upon which they would put the engine on the starter and pray for rain.

These kind of trials are a whole lot more fun to do in real life than in a simulator since the results have a way of varying from bad to worse
