Your argument that mobile phones or 'cell phones' do not interfere with the normal operation of planes is seriously flawed.

I site Cross Air flight LX 498 which crashed just after taking off from Zurich Airporton Jan 10 2000. Its navigation system was disrupted by mobile phone use and it crashed killing 10 passengers and the entire crew.

Secondly, I site an incident on Christmas eve of 2000 when a plane approaching 1400ft suddenly turned right and climbed. The crew had to resort to manual control to correct the flight path. It is suspected that a call to a passenger's cell phone caused the incident. All other possibilities were ruled out.

And lastly, I site The incident in early January of 2001 when a Slovenian airliner made an emergency landng after a mobile phone left on in someone's luggage (let alone being used by a passenger) caused a false "fire-on-board" warning, which forced the plane to make an emergency landing.

I would also like to add that in 2001 Faiz Chopdat flying from Luxor to Manchestor repeatedly refused to turn off his mobile phone. He was subsequently sentenced to four months imprisonment charged with exposing many people to mortal danger.

I hope youcan see that there is evidence suggesting that mobile phones or 'cell phones' are linked with mechanical problems in planes and that the use of mobile phones or 'cell phones' on planes is at best inconvenient, and at worse a criminal offense or the cause of fatalities.

Please reconsider using your mobile phones or 'cell phones' on planes or do not fly!!! For you own safety and that of innocent people who abide by the safety rules in place.
