Did Computer Game Or
Laptop Send 747 Out Of Control? - Catastrophe Just Averted

A COMPUTER game may have sent a jumbo jet with 400 passengers on board plummeting out of control, it was revealed yesterday.
 
The Qantas plane first soared 700ft, then rolled on its side and went into a sickening dive after its computerised autopilot jammed as it circled over London. The quick-thinking pilot took over manual control and landed safely.
 
Investigators now believe the malfunction could have been caused by passengers using laptop computers or personal CDs or playing with electronic games. A shocked air safety expert said yesterday in Sydney: "If this goes on, it's only a matter of time before we have a catastrophe on our hands."
 
The drama came at the end of a 22-hour flight from Sydney. Cabin staff asked passengers to switch off games or computers which could interfere with navigational equipment as the plane prepared to land. But it is thought some ignored the request.
 
As the plane took its place in a holding pattern waiting for air traffic controllers to give permission for descent to Heathrow it suddenly soared, flipped on to its side and plunged before levelling out.
 
The scare, disclosed for the first time yesterday, is one of 50 involving Australian airlines logged by the country's air safety experts since 1994.
 
Terrifying incidents include reports of planes rolling, swerving up and down - known as "porpoising" - and deviating from flight paths.
 
There have also been unexpected decreases in cabin pressure and unintelligible messages appearing on flight management systems.
 
Malfunctions have been linked to mobile phones, laptop computers, video cameras, hand-held video games and radio-cassette and CD players.
 
An investigator said: "Passengers will insist on continuing to use these devices after they've been told to turn them off."
 
Australia's worried Civil Aviation Safety Authority is now considering strict new rules.
 
Airlines in Britain, the US, New Zealand and Canada have banned mobile phones during flights.
 
A spokesman for BALPA, the British pilots association, said: "There's still no conclusive proof that electronic equipment can affect an aircraft. But we can't take risks."
 
British Airways said: "We don't let passengers use electronic equipment during take-off or landing."
