A new study conducted by Carnegie
Mellon University says the use of cellphones on airplanes can "impact a plane's navigation or other systems."
This study wasn't conducted in a lab, but on actual flights across three airlines in the Northeast and found that
"several" cellphone calls are typically made on commercial flights during takeoff and approach (no surprise
there; that's when you get the best signal) -- the most critical stages where accidents occur. Seems that with
the assistance of the cellphone
, researchers were able to stow a broadband antenna attached to a portable spectrum analyzer in a piece of
carry-on luggage. The FCC, remember, is conducting its own independent study of in-flight cellphone usage which should
wrap up by year-end. Whatever, let's be clear, we don't want to sit tethered to some blowhard detailing the advantages
of English style knitting over Continental, mkay? This isn't just an issue about safety.
