Cell phones may cause instruments to malfunction, and they only work near airports on landing and take off under 2000 feet under 250 mph. The satellites they work with lose their signals when flying faster. DUH.

From your article QUOTE-"Passengers react differently on this warning, someone switches off the phone, and someone thinks that it is only a precaution. In this case people make calls during take-offs and landings,
they don't pay attention to requests of neighbors or even crewmen. And it is so, despite the fact that all airlines prohibit to use cell phone during the flight.
This ban, which was appeared as an extra insurance, is of vitally importance today. We've already known instances in which equipment and navigation equipment, in particular, was affected by a cell phone
. At least one air crash
was occurred because of a working mobile phone and it is a forcible argument to ban all wireless phones aboard the plane. ...Look, a one-minute call in the air was much more expensive than a usual cell phone call and, naturally, people used a cheaper service when they had a choice.....Specialist in equipment negatively took this announcement and in 1996 U.S. Federal Aviation Administration asked nonprofit organization
to research this problem. As a result of their study was an article, where the specialists said that cell phones didn't operate on airplane systems
. They also confirmed that all the bans shouldn't be repealed because theoretically such interference could take place
.....First alarm was set when cell phones became widely spread and equipment errors became more often but still there were no direct evidences. Till 2000 some of the countries didn't joint to the ban against cell phones but an air crash of the flight number LX 498 Crossair (Saab 340) considerably changed the situation. It was not far from Zurich on the 10. of January 2000. Ten passengers and a whole crew perished in that air crash. For a long time the results of flight recorders decoding were not announced but at last it was a sensation. One of the reasons of the crash was an SMS message, which was received by one of the passengers, and a next cell phone conversation. Navigation monitoring devices showed wrong data at that moment, what led to a crash. Comments of independent experts were not comforting, they said that crew could improve the situation but it also made a mistake and crash was inevitable. Everybody agreed that an airplane fortune depended on crew actions and crew professionalism after electrical systems stopped working. Those countries which hadn't joint to the ban before, hurried on to do it. After that this air crash was forgotten."
DUH- maybe the people using the phones on the plane at gunpoint forced by terrorists, inadvertently brought down the plane by screwing up the instruments the terrorists that had learned to fly Cessnas were trying to fly at supersonic speeds into buildings did it. DUH.
I'll excuse you because maybe you haven't advanced beyond grade 3 reading comprehension, but read on, sonny.
Read this article, Lew, the whole thing.
As for the original Flight 93, this was perhaps little more than a decoy flight, though its passengers have entered modern folk-lore as the plucky American heroes who took on evil Muslim terrorists with their bare hands. This myth is based on the cell phone calls allegedly made from the stricken plane but, as Professor Dewdney and others have pointed out, it is not actually possible to use cell phones on aircraft flying at altitudes above 2000 feet and at speeds in excess of 230 mph. Since Flight 93 was at cruising speed and altitude when the calls are alleged to have been made, it is likely they were made from the ground if they were made at all.
This of course means we must treat with some suspicion either the people who allegedly made them, the relatives who reported them, or both.
There is another reason why the four original planes might well have had no bona fide innocent civilian passengers on board and that's to do with what we might, with some irony, call the 'Flight 93 Syndrome', i.e., the excessive and uncontrolled use of cell phones. They may not be much use above 2000 feet, but cell phones can be used at airports and on planes that are taking off or landing.

"The cell phone calls from the aircraft could not have happened. I am a National Security Agency trained Electronic Warfare specialist, and am qualified to say this. My official title: MOS33Q10, Electronic Warfare Intercept Strategic Signal Processing/Storage Systems Specialist, a highly skilled MOS which requires advanced knowledge of many communications methods and circuits to the most minute level. I am officially qualified to place severe doubt that ordinary cell phone calls were ever made from the aircraft.
It was impossible for that to have happened, especially in a rural area for a number of reasons.
When you make a cell phone call, the first thing that happens is that your cell phone needs to contact a transponder. Your cell phone has a max transmit power of five watts, three watts is actually the norm. If an aircraft is going five hundred miles an hour, your cell phone will not be able to 1. Contact a tower, 2. Tell the tower who you are, and who your provider is, 3. Tell the tower what mode it wants to communicate with, and 4. Establish that it is in a roaming area before it passes out of a five watt range. This procedure, called an electronic handshake, takes approximately 45 seconds for a cell phone to complete upon initial power up in a roaming area because neither the cell phone or cell transponder knows where that phone is and what mode it uses when it is turned on. At 500 miles an hour, the aircraft will travel three times the range of a cell phone's five watt transmitter before this handshaking can occur. Though it is sometimes possible to connect during takeoff and landing, under the situation that was claimed the calls were impossible. The calls from the airplane were faked, no if's or buts. "

"There are so few places these days where we can escape cell phones, pagers, BlackBerrys and CNN. Please let my airline flight be the last comfortable, quiet cocoon that is left to me where I can get lost in my own thoughts."
Silverman's wish is at least several years from being granted, because the movement to end the ban on airborne cell phones still faces several hurdles.
few airlines already offer moderately fast Internet connections, and the commission moved Wednesday to permit high-speed Internet connections. Air travelers could be routinely surfing the Web by 2006.
Passengers are now allowed to use electronic devices without radio transmitters — such as video games, CD players and laptops — above 10,000 feet. Some airlines also offer satellite TV. But things like cell phones and pagers are banned from takeoff to touchdown.
The only way passengers on domestic flights can communicate with the ground is on a type of phone found on about 1,500 jets, usually built into seat backs. The phones aren't very popular because of complaints about high cost and poor reception.
Cell phones usually don't work at high altitudes. When they do, they simultaneously communicate with hundreds of cell towers on the ground, clogging networks.
But it's now possible to place a small cell phone tower on each airplane
to receive signals from passengers' cell phones and relay them, directly or by satellite, to designated towers on the ground
The new cell systems would cost about $100,000 per plane but might give the financially-pressed airlines a new source of revenue based on a per-call surcharge.
If the FCC eventually approves passenger use of cell phones, the FAA still must rule on their safety.
The issue of radio frequency interference has become more critical as jets rely increasingly on sophisticated computers and electronic devices. For example, many planes now use the Global Positioning Satellite system, and the weak signal from satellites in space is easily distorted by other radio broadcasts.
There, I hope I answered all your stupid answers. Remember, there are no stupid questions, but a lot of uninformed stupid answers from people who can barely read. Just like bucky used to do, he shot himself too often in his own toes, until he blowed both his pins off and didn't have a leg left to stand on.
LEW says-Cell phones do in fact work on Planes......Ive read the experiment by Germar Rudolf and yes I guess his didnt work...but that doesnt mean they cant work on planes
Think about it, If they couldnt work at all why are they forbidden in the first place? Why not say hey your phones arent going to work so dont try..."
Best read that article and especially the parts I underlined sos' yu kin git thu gist of wut German Rudolf the red faced raindear said, DUH.
