The FCC in the US finally realized that talking and using cellphones on planes is safe. The FCC just removed the ban against such use of cellphones for data and calls in the air. Now the Department of Transportation is working on their own ban for cellphone calls in the air. It seems like everyone is unanimous about not having people chatting next to them on the plane. I agree with that sentiment though airlines for decades had payphones in the back of every seat that were only recently removed.
In short it seems like data is going to get the green light while phone calls are going to stay muted. I doubt that it will stay that way but the constant march of technology is inevitable. It just saddens me to lose one more place where there was a momentary disconnect with the outside world.
