Air Crash Investigation: British Airways Flight 5390

The aircraft, captained by Tim Lancaster and co-piloted by Alastair Atchison, was BAC One-Eleven Series 528FL G-BJRT. It took off at 7.20 am local time, with 81 passengers, four cabin crew and two flight crew. Co-pilot Atchison handled a routine take-off, and relinquished control to Lancaster as the plane established itself in its climb. Both pilots subsequently released their shoulder harnesses, while Lancaster loosened his lap belt as well. At 7.33 am, the cabin crew had begun to prepare for meal service. The plane had climbed to 17,300 feet over Didcot, Oxfordshire. Suddenly, there was a loud bang, and the fuselage quickly filled with condensation. The left windshield, on the captain's side of the cockpit, had suffered a catastrophic failure. Lancaster was jerked out of his seat by the rushing air and sucked head first out of the cockpit; his knees snagging onto the flight controls. This left him with his whole upper torso out of the aircraft, and only his legs inside. The door to the flight deck was blown out onto the radio and navigation console, blocking the throttle control which caused the plane to continue gaining speed as they descended, while papers and other debris in the passenger cabin began blowing towards the cockpit. On the flight deck at the time, flight attendant Nigel Ogden quickly latched his hands onto the captain's belt. Susan Price and another flight attendant began to reassure passengers, secure loose objects, and take up emergency positions. Meanwhile, Lancaster was being battered and frozen in the 500mph slipstream, and was losing consciousness due to the thin air. Because the aircraft had suffered an explosive decompression, Atchison began an emergency descent, re-engaged the temporarily disabled autopilot, and broadcast a distress call. Due to rushing air on the flight deck, he was unable to hear the response from air traffic control. The difficulty in establishing two-way communication led to a delay in British Airways being informed of the emergency and consequently delayed the implementation of the British Airways Emergency Procedure Information Centre plan. Ogden, still latched onto Lancaster, had begun to suffer from frostbite, bruising and exhaustion. He was relieved by the remaining two flight attendants. By this time Lancaster had already shifted an additional six to eight inches out the window. From the flight deck, the flight and cabin crew were able to view his head and torso through the left direct vision window. Atchison eventually received clearance from air traffic control to land at Southampton, while the flight attendants managed to free and hold onto Lancaster's ankles for the remainder of the flight. By 7.55 am the aircraft had landed safely on Runway 02 at Southampton. Passengers immediately disembarked from the front and rear stairs, and emergency crews retrieved Lancaster. [wikipedia]
