Ted Stevens and former NASA chief Sean O'Keefe that crashed into a remote Alaska mountainside during a fishing trip, killing Mr. Stevens and four others and stranding the survivors on a rocky, brush-covered slope overnight. The plane hit the ground with so much force that it left a 300-foot gash on the slope, federal investigators said. (AP Photo/Alaska State Troopers)
