OK, but the ill fated plane should be clearing the runway threshold by 50’ or so. The point here is that the plane should be landing 1000’ to 1500’ from the threshold. The purpose of this is to allow adequate clearance for the landing gear over the threshold. This flight seemed to actually contact the rock berm between the concrete runway and San Francisco Bay! Ouch! It may have “collided” with what?

It may have “collided” with what?

I don't know, but the emergency channel had some individual reporting that a 'target' had been dropped at the airport or in the water after the crash.

Not clear if 'target' was human or mechanical.
