THIS IS BASED ON RUMOUR...
Seems that on departure, for some reason or another, the Aircraft hit the approach lights (for the other side).
It is not clear if the aircraft got airborne before the runway end or not.
Flap(s) stuck at take off setting, (multiple) tyre damage.
Aircraft burnt/dumped fuel, returned and landed.
Apparently some part of the undercarriage went through some part of the wing, I am not sure of the extent of this damage, or if this occured on departure or landing.
I suppose the pilot could have got hurt during the departure or landing.
