I have also seen this. In theory your mobile phone can affect computers and such on the plane. Now you may or may not believe this however in the interest of my personal safety pls turn off your phone if you're on a plane with me. I'd rather be safe than sorry. Also, I value all of my passengers, crew and equipment so if you don't mind, don't take the chance.

While on the subject of phones do you guys (mostly) and gals realize how sensitive today's cell phone microphones are? When you call us we can hear everything going on. So please, if you're in the proverbial John, don't call me. Thanks
