Ok, but can they now do some testing on a commercial-size airplane? I do not think a terrorist getting into the USA will have the means to hijack a military plane and crash it appropriate into a nuclear facility. They proved, on the other hand, that commercial planes are much easier to acquire under force.
Besides, the kenetic enegy being absorbed by a 757 or 747 would be much more substantial at 500 MPH. Ok, I just want them to toast a commercial jetliner for my amusement, but considering the things our tax dollars typically get wasted on is without amusement ...
And why couldn't the remote pilot the place onto the target instead of placing it on a rail?
