I dont see how a rectangular object 22m by 13m can be part of the plain.

777s are only 6.2m wide

If it was a 13m section of the upright tail, connected to 22m of fuselage, it would appear as an "L" shape.

And if was a wing connected to part of the fuselage, it would appear as a T or L shape.

Cab someone explain how it could be part of the wreckage?
