……found on a travel weblog: “Wow and you did not give the reason why you cannot use a cell phone on a plane! OK, let me tell you why. It interferes with the planes on- flight communication, meaning the piolet and flight attendants cannot talk to one another. No cofee or pee pee break for the poilet. That is the ONLY reason you cannot use them. I just had a flight where I forgot to turn mine off- no big deal.”
