- rapsey 9y agoYou can not make cell phone calls during flight.
- 6nf 9y agoI've done it. It's possible. Why do you think it's not?
- rapsey 9y agohttp://edition.cnn.com/2014/04/14/tech/mobile/phones-in-flight/index.html http://edition.cnn.com/2014/04/14/tech/mobile/phones-in-flig... > The maximum distance at which a phone can still make calls and send texts varies depending on the type of tower and transmitter, but an airplane would have to be no more than 10,000 feet in the air for any cell phones on board to still have a signal, If the plane offered cell connectivity itself it's another matter entirely. Those planes sure did not.
- 6nf 9y agoThe planes were lower than 10,000 feet at the time of the phone calls
- rapsey 9y agoWere they? What is your source on that? People who checked the info found the opposite. https://www.bibliotecapleyades.net/sociopolitica/esp_sociopol_911_47.htm https://www.bibliotecapleyades.net/sociopolitica/esp_sociopo...
- KozmoNau7 9y agoMany airlines have repeaters on their planes, allowing people to place cell phone calls and send/receive text messages, usually at inflated prices. So why do you think it's impossible?
- rapsey 9y agoBecause those flights did not and US airlines in general don't at least not then.
- dogma1138 9y agoNot in 2001 tho, I have no beef in this but people forget the times...
- 6nf 9y agoYea but clearly these planes were not flying at 30,000 feet so regular cell tower calls would have worked
- rapsey 9y agoSource? Not only is there a height limit, there is a speed limit for call handoff between towers. It's pretty low at ~100mph. Way below airplane speed.

- flukus 9y agoThey seem to work fine on high speed rail.
- dogma1138 9y agoAlso with much older cellular technology, in 2001 the US mostly used 2G TDMA/CDMA networks with carriers like Verizon still relying on older AMPS systems on the 850mhz band. I'm not entirely sure how that would've worked, even today having a phone call from low altitude is pretty hard jets are pretty decent Faraday cages and the speed is just as much of a problem as the altitude. There is a difference between having the cellphone pining a tower or even managing to get a short data packet from time to time and having an uninterrupted phone call. I don't think there 9/11 was a "conspiracy" I think there was just a lot of random information that amplified to conspiratorial levels.
