 The stealth technology from the downed F-117 may have been acquired by Russia and China, but the United States did not destroy the wreckage because its technology was two decades old.Some American sources state that a second F-117A was damaged during the same campaign, allegedly on 30 April 1999; the aircraft returned to base, but it supposedly never flew again.Use of the aircraft as part of Operation Allied Force continued, and it was later used in the Operation Enduring Freedom in 2001 and Operation Iraqi Freedom in 2003.
