Yea 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.

- 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.
- flukus 9y ago> jets are pretty decent Faraday cages No they aren't, you can make calls perfectly fine from inside a jet, 4g reception works too, you're even allowed to do this until takeoff now.
- 6nf 9y agoI know I'm supposed to turn my phone to flight mode but I often use my phone on planes so I know it works. I've been doing this for years. Jets are not faraday cages. The speed of the jet slows down your connection and you need to be over a city but it works just fine. I can browse the web, watch youtube vids, etc. I don't make calls on a plane cause that would just annoy everyone around me but I'm confident it will work.
