The Urgent Call to "Return to Base" & The Chopper Strange Movements Make No Sense

Investigators are going to have to look at every possible reason a military Black Hawk Helicopter could crash into an American Airlines passenger jet landing at Reagan Airport in D.C.
The calls from air traffic controllers for the helicopter to “return to base” raise serious concerns over what may have caused this crash.
We even pulled the altitude and flight tracking data that revealed sharp zig-zags and a sudden drop in altitude moments before the crash. Here are the possible reasons behind the disaster:

Mechanical Failure
Air Traffic Control Failure
Human Error
Nefarious Action
Pilot Suicide
Computer Hack

We have the audio of that “return to base” call, as well as the altitude data you have to see and hear to believe.
