Further weapons tests occurred between 22 May and 7 June 2001, with mixed results. While missile accuracy was excellent, there were some problems with missile fuzing..." In the first week of June, in the Nevada Desert, a Hellfire missile was successfully launched on a replica of bin Laden's Afghanistan Tarnak residence. A missile launched from a Predator exploded inside one of the replica's rooms; it was concluded that any people in the room would have been killed. However, the armed Predator did not go into action before the September 11 attacks.
