There's also probably a bunch of other junk down there to throw false positives. You'll make more selling the scrap metal you haul up than you will selling the meteorite (still won't be a money-maker though).

Depends on whether the DoD believes it was a rock. Delaware is pretty close to D.C.

We have other ways to determine the nature of a falling object. Much can be assertained from its trajectory, deceleration, and luminance. It’s trivial to determine that this was not a reentry vehicle.

Exactly. If that was a vehicle/projectile, even watching the dashcam videos of it, it's quite obvious that parts of it underwent rapid, unplanned desintegration. So it likely would't have done anything significant if it was (it was not.)

Well, we think it’s a rock ... <insert Superman reference here>
