Saw that. A pretty interesting and poignant story after all these years since the attacks. The conspiracy theorists are already concocting stories that it was planted there by lowering it on a rope (a battered old rope is attached to this piece of the plane) in order to further cement the "proof" that civilian airliners hit the Twin Towers that day (i.e. the predictable "Inside Job" and Truther idiots).
It'll be interesting to follow the developments surrounding this find.
