The aircraft, commanded by Tim Lancaster and co-piloted by Alistair Atchison, was a BAC One-Eleven Series 528FL with the registration code G-BJRT. It took off at 7:20 AM, local time, with 81 passengers, 4 cabin crew, and 2 flight crew on board. Co-pilot Atchison handled a routine liftoff, and relinquished control to the commander 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, and was moving over Didcot, Oxfordshire. Suddenly, passengers heard a loud bang, and the fuselage quickly filled with condensation. The left windshield, located on the commander's side of the cockpit, had suffered a catastrophic failure. Lancaster was jerked out of his seat by the rushing air and blown head first out of the cockpit; however, his knees had snagged onto the flight controls. The door to the flight deck was blown out onto the radio and navigation console, 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 commander's belt. Susan Price and another male flight attendant began to reassure passengers, secure loose objects, and take up emergency positions.

It was immediately apparent that the aircraft had suffered an explosive decompression, so the copilot began an emergency descent, re-engaged the temporarily disabled autopilot, and broadcast a distress call. Due to the rushing air on the flight deck, Atchison was unable to hear the response from air traffic control. The difficulty in establishing two-way communication indirectly 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. However, by this time, Lancaster had already shifted an additional 6 to 8 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.

The co-pilot eventually received clearance from air traffic control to land in 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 in Southampton Airport. Passengers immediately disembarked from the front and rear stairs, and emergency crews retrieved Lancaster.

Despite his serious injuries, Tim Lancaster survived. He was taken to Southampton General Hospital, where he suffered from frostbite, bruising, shock, and fractures to his right arm, left thumb, and right wrist. In addition, one flight attendant received minor cuts and bruises to his arm. Everyone else left the airplane unhurt.



Wow. Imagine being sucked out the window and pinned to the front of the plane while the co-pilot landed it!!

I saw something about this on the History Channel when I was flipping channels. Amazing that nothing fatal occurred.

how was he able to breathe at that altitude...i thought people died from lack of oxygen and feezing temps at that height

I will admit that I have no "real" knowledge of the physics or dynamics behind high altitude air travel but...

After the plane decompressed wouldn't air be rushing INTO the cockpit, therefore pushing the pilot back in? Kind of like sticking your hand out the window of a moving vehicle. The wind pushes your hand back. Decompression may have initially sucked him out but wouldn't that have ended rather quickly as the pressure equalized and then started to very forcefully push him back into the plane?

Also, I saw the mythbusters explosive decompression episode, end they were unable to recreate this situation.

his head and torso were pinned to the outside of the plane by the 300 mph airspeed, i'm guessing.

They specifically was testing if a bullet would cause explosive decompression.

The pressure is not high enough and the hole is too small. Explosive decompression only occurred when a hole the size of a window was made with explosives. Even then, the rush of air could not suck Buster completely out of the hole. Lastly, there are proven instances of explosive decompression where the plane was still able to maintain control and land.

Saw this in one of those discovery channel (or history) flight stories. The pilot lived and flew again, afaik.

Thats exactly what they showed. He was pancaked outsize with the lowerhalf inside, with the flight attendent holding on to his legs.

I just saw this episode on Discovery Channel's "Mayday". The most amazing story ever!! A huge KUDOS to the flight crew on that day....but especially to the First Officer. How he kept his wits together to deal with that situation is beyond me...even more amazing than the emergency landing made on the Hudson River in NYC!

My utmost regards and repect!

The air flowing over the window is moving much faster than that in the cockpit, and hence will have a much lower pressure. It's similar to a venturi nozzle which draws fuel in from air rushing over a hole to create suction.

17,000 feet isn't that high, and the first thing pilots are trained to do in the event of a decompression is to descend to a lower altitude ASAP. He may have temporarily lost consciousness from hypoxia but it shouldn't have been fatal.

An airplane is flying at 17,000 feet after taking off from a treadmill when explosive decompression occurs. The pilot is temporarily suspended in mid air via the wind but he is still inside the airplane. Does the airplane weigh the same or less than it did when the pilot was sitting in his seat?

With a decompression, they would have made an immediate emergency descent to 10,000 feet. So the guy would have been able to breathe just fine.

If you read the story, it says they did in fact make an emergency descent, as required in the situation.

Your time of useful consciousness at FL170 is between 20 and 30 minutes. Somewhere in there, you would pass out, and then somewhat later, you would die, without supplemental oxygen. The emergency oxygen for the pax is only a few minute's worth, just enough to make the emergency descent with a little to spare.

So, with a decompression, it's imperative that you get down to FL100 or so as soon as possible.

At FL350 for example, everyone will be unconscious within one minute without oxygen.

At FL410, it's about 15 seconds.

A very rapid decompression, such as from a window blowing out, can reduce the above times significantly because your lungs can forcibly empty with the pressure change.

This is why the pilots are on oxygen at high altitudes.

At middle altitudes, if one pilot leaves the cockpit, the other must go on oxygen.

In fact, the operational ceiling of airliners such as the 747 is not only dictated by the physical limit of the airframe, but by how fast it can descend to FL100. I do not know the requirement offhand, but an airliner must be able to descend from it's max height in a certain amount of time, in order to be certified to operate at that height.

It must be able to descend fast enough to ensure that no one will be harmed in the event of a sudden depressurization.

Less. The plane is now missing a windshield and the lower pressure air is less dense.
