Huh, So iPhones Can Interfere With Cockpit Instruments

NASA has confirmed that iPhone's and other portable electronic devices interfere with instruments.  There are numerous other incidents of suspected, but unconfirmed, interference too.  Most passengers suspect the requirement to turn off their phones is unnecessary, but it turns out there is some evidence behind this one.  Don't worry, there are plenty of other rules at airports and in air that don't make any sense and you can complain about.
