Airplane mode

Airplanes probably don't actually need you to turn your wireless off. But to do so on the XO-1 go to a Developer Console, or the Terminal Activity and issue the following commands:

1. Disable wireless

rmmod usb8xxx

1. Enable wireless

modprobe usb8xxx

OR

Go to the Terminal Activity and type:

 sugar-control-panel -s radio off
 sugar-control-panel -s radio on
