Passengers get really annoyed every time a flight attendant tells them to turn off their phones and devices while the plane is taking off or landing, but they begrudgingly comply.
Some angry phone addicts will even argue they read an article online that said they don't really need to turn their phones off anymore, because there is a picocell on the plane.
Well, they're right as long as they're on a plane equipped with picocell technology, but chances are they're being told to turn their devices off because the plane does not have a picocell.
And maybe if passengers understood that cell phone signals bounce off multiple towers, which makes it hard for pilots to clearly communicate with control towers, they would comply without all that grumbling!
