ehurtley said:AirPort and Bluetooth will *NOT* interfere with anything on the plane. (Other than possibly other people trying to use AirPort or Bluetooth.) Neither will cell phones. (Nextel possibly, GSM and CDMA are 100% safe.) It's all scare tactics. Not a single incident has ever been proven to have been caused by passenger-carried common consumer electronics.
It's not really used as a scare tactic. It's used to make sure passengers are alert during takeoff and landing. The majority of airplane problems happen during takeoff or landing, and if you have half the people talking on their cell phones you don't have their attention in the case of an emergency and you have to tell them things to do. Look at people driving their cars on their cell phones, so many accidents are caused by that alone. But ya, electronics such as cell phones and computers don't cause interferance with aviation radios as they use completely differnt frequencies.
