Cell use on planes: Really a danger?

(CNN) — You know who you are. You leave your phone on during flights, maybe do a little text messaging and otherwise break rules about cell phone use on planes once the doors close for departure.

“This is an absurd rule. I never turn (mine) off. I may text or browse the Web, but I never talk on the phone,” one CNN.com reader commented recently.

On the other side of the aisle are passengers who abide by the safety instructions and warnings, worried that cellular signals may indeed interfere with cockpit instruments.

Take those two camps and add passengers who say either way, listening to fellow travelers chatter on the phone would be annoying, and you have a heated debate — sometimes literally in the airplane aisles.
