This fascinating program traces the post-World War II attempts to build stealth - or Low Observable - aircraft that are invisible to radar and infra-red heat sensors. You'll view the F-117A Nighthawk ground attack aircraft; the B-2 Spirit heavy bomber; the YF-22 (F-22 Raptor); the YF-23A Black Widow II, which lost out to the YF-22 in the U.S. Air Force's Advanced Tactical Fighter competition; and many others. 1 hour. #00V9668
