Unsafe At Any Airspeed? Cellphones and other electronics are more of a risk than you think

The article presents clear evidence that devices are on during flights, some even transmit in the GPS range, calls are being made and the airplanes are fine.

We were able to clearly identify some cellphone signals that originated from on board the aircraft [again, see chart, "Cellular Stands Out"]. Ours was a conservative estimate, since a call made at the other end of the cabin from the instrumentation would be below the threshold we could observe. Our measurements also found emissions from other onboard sources--devices used by passengers--in the frequency used by GPS.

Our research shows clearly that, in violation of FCC and FAA rules, calls are regularly made from commercial aircraft. Results from our analysis imply that calls from on board scheduled commercial aircraft in the eastern United States occur at a rate of one to four per flight. In addition, we saw other signals that suggest that at least one passenger neglects to turn off his or her cellphone on most flights.
