But wait. You're quoting the guy that designed that stuff. And true, we're not going to allow some phone to mess around. But if the touchy grounding/shielding fails or goofs, it's better safe than sorry. And the actual reason behind "no phone or electronics while in flight", is that they actually do occasionally goof navigation and communication. Modern designs, not so much. Older aircraft and equipment, take your chances. edit: oh, and that turn right now was a joke. You should watch more worthless tv commercials.
