THE PENTAGON (CNN) — Military officials say a US aircraft accidentally dropped a 500-pound bomb on a US outpost in Afghanistan.
A camera strapped to a soldier's helmet was rolling when the explosion rocked the barracks.
Soldiers watch as a US aircraft is about to drop a 500 pound bomb on what the air crew thinks is a group of Taliban fighters.
But in a rare mistake, the bomb hits the US outpost instead.
Video has just come to light of a September 2012 incident in eastern Afghanistan.
Another reminder of the uncertainty of combat.
"This was a major mistake from a targeting perspective. The way targeting works is you have to get the coordinates right," Retired U.S. Air Force Col. Cedric Leighton told CNN.
An investigation determined the aircrew had the wrong coordinates.
"Unfortunately in wars, this does happen, but with precision-guided munitions, it's a much rarer occurrence than it used to be," Col. Leighton said.
We are told that no one was hurt, and investigators ruled it was an accident, so no one was punished.
But it could have been a terrible tragedy.
