Fear Factor

Members of the Army, Navy, Air Force and Marine Corps battle for $50,000 in challenges that take place on and around the USS Hornet aircraft carrier in Alameda, Cal. Included: a 100-foot drop from a helicopter; a stunt involving boa constrictors, live leeches, pig insides and rotten fish; and a challenge in which hand grenades get tossed from the top of a speeding truck. Also: a “home invasion” in Louisville.
