The investigation found that as the B-52 entered its final turn sequence around the tower, its airspeed indicator (ASI) was showing 182 knots (337 km/h; 209 mph). Although Holland increased the engine power after starting the turn, his input came too late to maintain the aircraft's airspeed, as the B-52 turbofan engines take up to eight seconds to respond to throttle commands. The ASI was available to all four aircrew members, but they allowed the aircraft's airspeed to continue decreasing.
