From the BBC report
A woman claimed her son managed to break a door and get out on to the wing of the plane.
- break!! I guess another one who didn't listen to the safety brief or read the card?
I can see no reference to anyone 'standing' on the wings?
To add
He said the crew opened the main doors at the back and front of the plane, where the inflatable chutes drop down, but not the ones over the wings.
- QED?
