AirNav Radar Box — AWACS for your laptop

From Jonathan Margolis's review in his "technopolis" column in today's Financial Times "How To Spend It" magazine: "Hook the AirNav Radar Box up to a PC (sorry, no Macs), place the antenna close to an office window, and you can turn your computer screen into the same live view of the aviation around you as an air traffic controller. It is unbelievably diverting. Watch in real time every aircraft for hundreds of miles, each identified by flight number, aircraft type, altitude, heading and speed, each updated every second. You can even click on the blip to see the actual aeroplane or one like it. Quite amazing."

Whip this puppy out on your next WiFi-enabled plane flight and take it to the next level.

Of course, once you get on the ground, all bets are off.

Considering that an AWACS plane costs $270 million, a snip at £389.95 ($642).
