On June 28, 2005, a four-man Navy SEAL reconnaissance team under Operation Red Wings was ambushed in northeastern Afghanistan—as depicted in the book and film Lone Survivor. A quick reaction force was dispatched. Turbine 33, carrying eight Navy SEALs and eight members of the 160th Special Operations Aviation Regiment, was struck by a rocket propelled grenade—careening the dual rotor Chinook toward the rugged peak of Sawtalo Sar. Dr. Tony Brooks, a former Army Ranger, discusses his bestseller "Leave No Man Behind,"  a first-hand account of the daring recovery of Turbine 33 and the subsequent search for the remaining compromised Navy SEAL recon team—one of whom was Marcus Luttrell, the lone survivor.
