British Airways Flight 5390

British Airways Flight 5390 was a scheduled passenger flight from Birmingham Airport, England to Málaga Airport, Spain. On 10 June 1990, shortly after takeoff, the BAC One-Eleven operating the flight suffered an explosive decompression after an improperly installed windscreen panel separated from its frame, causing the plane's captain to be blown partially out of the aircraft. The aircraft landed at Southampton Airport with no loss of life.

Aircraft
The aircraft operating Flight 5390 was a BAC One-Eleven 528FL registered as G-BJRT. The aircraft first flew on 8 February 1971 and was delivered to Bavaria Fluggesellschaft on 26 February 1971. It was later transferred to Bavaria Germanair in 1977, Hapag-Lloyd Flug in 1979, British Caledonian in 1981, and finally to British Airways in 1988.

Crew
The captain of the flight was 42-year-old Timothy (Tim) Lancaster, who had logged 11,050 flight hours, including 1,075 hours on the BAC One-eleven; the copilot was 39-year-old Alastair Atchison, with 7,500 flight hours, with 1,100 of them on the BAC One-eleven. The aircraft also carried four cabin crew and 81 passengers.

Incident
Atchison handled a routine take-off at 08:20 local time (07:20 UTC) then handed control to Lancaster as the plane continued to climb. Both pilots released their shoulder harnesses and Lancaster loosened his lap belt. At 08:33 (07:33 UTC) the plane had climbed through about 17,300 feet (5,300 m) over Didcot, Oxfordshire, and the cabin crew were preparing for meal service.

Air Steward Nigel Ogden was entering the cockpit when there was a loud bang and the cabin quickly filled with condensation. The left windscreen panel, on Lancaster's side of the flight deck, had separated from the forward fuselage. Lancaster was propelled out of his seat by the rushing air from the decompression and forced head first out of the flight deck. His knees were caught on the flight controls and his upper torso remained outside the aircraft, exposed to extreme wind and cold. The autopilot had disengaged, causing the plane to descend rapidly. The flight deck door was blown inward onto the control console, blocking the throttle control and causing the aircraft to gain speed as it descended. Papers and debris were blown into the flight deck from the passenger cabin. Ogden rushed to grab Lancaster's belt, while the other two air stewards secured loose objects, reassured passengers, and instructed them to adopt brace positions in anticipation of an emergency landing.

The plane was not equipped with oxygen for everyone on board, so Atchison began a rapid emergency descent to reach an altitude with sufficient air pressure. He then re-engaged the autopilot and broadcast a distress call, but he was unable to hear the response from air traffic control because of wind noise. The difficulty in establishing two-way communication led to a delay in initiation of emergency procedures. Ogden, still holding on to Lancaster, was by now developing frostbite and exhaustion, so chief steward John Heward and air steward Simon Rogers took over the task of holding on to the captain. By this time Lancaster had shifted several inches farther outside and his head was repeatedly striking the side of the fuselage. The crew believed him to be dead but Atchison told the others to continue holding onto him, out of fear that letting go might cause Lancaster to strike the left wing, engine, or horizontal stabiliser, potentially causing damage to the aircraft.

Eventually, Atchison was able to hear the clearance from air traffic control to make an emergency landing at Southampton Airport. The air stewards managed to free Lancaster's ankles from the flight controls while still keeping hold of him. At 08:55 local time (07:55 UTC), the aircraft landed at Southampton and the passengers disembarked using boarding steps.

Lancaster survived with frostbite, bruising, shock, and fractures to his right arm, left thumb and right wrist. Ogden dislocated his shoulder and had frostbite on his face, with damage to one eye. There were no other major injuries.
