Could you use a cell phone aboard a plane in 2001?

I thought so
Am I wrong?

I think you mean could you use one at altitude.

On the ground, no problem.

At altitude, possibly, but it would be spotty and likely drop signal. Long distance high altitude flight would be a problem (say New York to Los Angles)_. More regional lower altitude flights would be better (say Paris to Berlin).

Today, as I understand it, for a consistent connection you have to connect to the planes WiFi and use data calling.

My question has to do with 9/11 …..

Could the passengers on 9/11 planes use their cell phones?

 

[Muhammed]

Could the passengers on 9/11 planes use their cell phones?

Yes. Several of them were making calls from flight 93.

 

[WorldWatcher]

Could the passengers on 9/11 planes use their cell phones?

Yes, the flight departed New Jersey and was operating over Pennsylvania enroute to San Francisco.

Since they were flying over populated areas that likely had good cell phone coverage access to a signal was probably pretty good.

In addition to regular cell phones, aircraft at the time were equipement with "Airphones" a credit card based accessory where you could place calls from the aircraft by swiping a credit card. Then it's not you handheld phone making the connection but dedicated equipmet on the aircraft used for the call - so much better.

So I was right in thinking so.

AMPS, Advanced Mobile Phone System was the original cell phone system, and it was analog. In February 2008 it was discontinued, and eventually we ended up where we are today with some reliance upon satellites.

In 2003 through 2008 in Florida flying a helicopter with an AT&T phone and a Nextel walkie-talkie type strapped on for the boss, and thus completely dependent upon cell towers, below 1500 feet or so the phones could be used, but lost calls were very common and reliable conversations very short in duration.

Above 1500 feet, both phones displayed NO SERVICE on the screen.

The phone calls in the official narrative were contrived, just scripts in a play meant to fool gullible people.

I thought so
Am I wrong?

Yes but it was often unreliable and disconnected a lot of calls.

The phone calls made on 911 were not made with cell phones but with satellite phones built into the planes.

The phone calls on 911 from the plane were not made with cell phones you moron

They were not scripted

 

[LA RAM FAN]

Yes. Several of them were making calls from flight 93.

disinformation,it was IMPOSSIBLE to make cell phone calls in 2001 when just over 8,000 feet and the commission said the airliners were at 30,000 feet.,after just 10,000 feet the service gets VERY Difficult and were talking 30,000 feet which is the average for airliners?

What about all those 9/11 calls?​

"Once you get to a certain height, you are no longer in the range of the cellular network, because cell phone towers aren't built to project their signals that high." ~~ Washington Post, 12/9/04

"Today's vote by the FCC is intended to address whether technology has improved to the extent that cell phone calls now are possible above 10,000 feet -- they weren't in the past." ~~ San Francisco Chronicle, 12/15/04

Question:

Given the known limitations of a cellular phone system in 2001, can you provide any evidence that the cell phone calls made by the passengers reported by the FBI could have been made from the altitudes , speeds, and for the durations indicated for each of them?

The answer is NO.

Scientific Experiments Conducted:

A. K. Dewdney who is a scientist, conducted a series of experiments using cell phones from a small propeller aircraft, over the city of London, Ontario in Canada. (He noted that, "not only is the cell phone technological base in Canada identical to its U.S. counterpart, but Canadian communication technology is second to none, Canada being a world leader in research and development."

Dewdney found:

Cell phone calls from commercial aircraft much over 8,000 feet are essentially impossible, while those below 8,000 feet are highly unlikely down to about 2,000, where they become merely unlikely. Moreover, even at the latter altitude (and below), the handoff problem appears. Any airliner at or below this altitude, flying at the normal speed of approximately 500 mph, would encounter the handoff problem. An aircraft traveling at this speed would not be over the cell site long enough to complete the electronic "handshake" (which takes several seconds to complete) before arriving over the next cell site, when the call has to be handed off from the first cell site to the next one. This also takes a few seconds, the result being, in the optimal case, a series of broken transmissions that must end, sooner or later, in failure. Source: http://physics911.net/cellphoneflight93

right PeterPilot ?

explain to him those calls were faked with voice morphing..

so to answer zebras question,YES you ARE wrong.
