Raspberry Pi 2 can be used to track aircraft.

This came thru the mailbox today

Software radio with a Raspberry Pi 2.

Installing GNU Radio and receiving aircraft radar with a USB TV tuner

The Raspberry Pi has been put to countless creative uses, with it's low cost and easy to use GPIO, coupled with a passionate and inventive community, giving birth to applications that have ranged from simple fun, to inspired and even profound.

Thru that article I found this little gem:

Watching planes with software-defined radio

Modern aircraft are fitted with “Mode S” transponders that can be interrogated by air traffic control radar in order to ascertain their position and heading. Hobbyist equipment for receiving these transmissions has been available for some time and typically costs hundreds of pounds. But it's now possible to re-purpose DVB-T hardware costing around £20 to create an SDR-based receiver.
