Military analyst gives detailed explanation of how the DC midair collision happened

I found this great detailed explanation by military analyst Sean Bell of how and why the Blackhawk helicopter collided into a passenger airplane in Washington DC.

Air traffic control rerouted the airplane to runway 33 in direct path with the Military Blackhawk helicopter. But the Blackhawk helicopter should have been flying at 200 feet and not 400 feet they were flying.

I customized this background and description. I also added the date and the captions that I proofread for you.
