Spirits Takeoff!
The "Spirit of California," a B-2 bomber, takes off during a base exercise, April 9, 2014, at Whiteman Air Force Base, Mo. The B-2’s low-observable, or "stealth," characteristics give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued, and heavily defended, targets.
