There are redundant systems on modern planes that can handle multiple failures. If they’re saying it’s fuel related my guess is dirty jet fuel. It would explain a stuck fuel valve. There’s lots of ground crew checks before flight, and one is checking the fuel tanks for contamination. Just a speculation.

This is the cheat code. Just stroke the man’s ego, and you can get anything you want.

“Furthermore it was said that a drone gun had triggered the panic, which is highly doubtful from a technical point of view.”

Anyone who’s seen the video can see it’s not a drone with a gun causing the panic. Although you couldn’t see it, that vehicle probably focused a high pitch sound to clear the road.

Edit: this is a different video than the original one I saw but it looks like they’re using the same technique here https://m.youtube.com/watch?v=CvY9sVUERV0
