I saw this clip a few months ago. Took me a while to find it again.
Most of you know by now that the JDAM (Joint Direct Attack Munition) family of bombs are GPS guidance systems strapped onto conventional dumb bombs, giving them great accuracy. Actually, they are intertially guided, with a GPS update, but close enough.
One pass by a B-2, and an enemy airfield is out of operation for quite a while.
