∞ Why do we need to turn off phones to fly?

Nick Bilton, for the New York Times:

Michael Altschul, senior vice president and legal counsel for CTIA, the wireless industry association, said a study that it conducted more than a decade ago found no interference from mobile devices.“The fact is, the radio frequencies that are assigned for aviation use are separate from commercial use,” Mr. Altschul said. “Plus, the wiring and instruments for aircraft are shielded to protect them from interference from commercial wireless devices.”

“Better safe than sorry” is the crux of the FAA’s rationale against allowing people to use electronic devices, but it seems pretty silly. Then again, so do a lot of government regulations.
