Wolfram Alpha has the coolest flight tracker ever
J Thoendell stashed this in Apps
Have you ever wanted to know where the planes flying overhead were going? If so, you finally have a way to find out.
If you head over to Wolfram Alpha right now and input "flights overhead" into the search box, the site will return all the planes that are currently over your position, their altitude, angle, and slant distance. The site even displays a Sky map to show where planes are in relation to the position of the sun and moon.
