(CNN) – Military officials say a U.S. aircraft accidentally dropped a 500-pound bomb on a U.S. outpost in Afghanistan.

A camera strapped to a soldier's helmet was rolling when the explosion rocked the barracks.

Soldiers watched the aircraft drop on what the air crew thinks is a group of Taliban fighters. But, in a rare mistake, the bomb hits the U.S. outpost instead.

The video has just come to light of this September 2012 incident in eastern Afghanistan, another uncertainty of combat.

"This was a major mistake from a targeting perspective," said retired U.S. Air Force Col. Cedric Leighton. "The way targeting works is you have to get the coordinates right."

An investigation determined the air crew 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," Leighton said.

Once the bomb is dropped, the soldiers begin to check on one another.

No one was hurt in the incident, and investigators ruled it was an accident, so no one was punished, but it could be been a terrible tragedy.
