Whenever a US helicopter goes down in Iraq, somebody in the US military always lies about it. It never is the truth: as in the helicopter was shot down by "enemy fire"--i.e. Iraqi rebel fire. It always is a convoluted story: that the pilot had chest pains before it was down; or that it collided with a potato tree as the pilot was landing it; or that it is not clear what really happened; or some weird mechanical error (which always happens over Ramadi), etc. Historians will find the lies around this war more massive than those around Vietnam.
