FAA to Finally Lift In-Flight Device Restrictions → Re: Overwhelm the registration system?

Because people don't understand that you can't make phone calls up in the air. There will ALWAYS some knitwit thinking you can.

actually, I have confirmed that you can send/receive texts and calls at anything below about 5000 feet. Past that, its just not happening. Cell towers do not like being hit and dropped at those speeds.
