I'm in the last row of the plane, backseat :-), so I get a good view, but why are there all these people looking up at the fuselage in the wing

And why is there a fire engine rocking up now as well ?

Now it is really getting busy under that wing, there are about 12 people milling around now, with torches , checking the underside of the wing, and now they got like a cheery lift to get a closer inspection going on

The guy on the left seems to be in charge, and from his body language I'm getting the vibe that this plane isn't going anywhere
