one helicopter carried a navy seal team and an air force combat controller, technical sergeant john chapman. as the seal team disem-barked, automatic weapons fire laced the helicopter's side while a rocket propelled grenade ripped into it. the crew chief yelled, "we're taking fire! go! go! go!" and the seal team rushed back inside. as the pilots added power to evade the heavy ground fire, the damaged helicopter bucked violently, causing navy seal petty officer 1st class neil roberts, who was standing on the ramp, to fall about 12 feet to the ground below. the helicopter escaped the ambush and crash-landed about seven kilometers north of where petty officer roberts fell. the second helicopter rescued the other seals and sergeant chapman but after returning to their base, they decided to try and rescue petty officer roberts.
