PHILADELPHIA (CBS) – On today’s APP-tastic and Outta SITE – PlaneFinder 3D.

Everyone spots a plane flying overhead from time to time – and it’s kind of fun to watch it go by – but odds are the plane you see isn’t the only one nearby.

PlaneFinder 3D shows you live air traffic overhead, letting you pan and zoom to get a sense of how many flights are within close proximity to you.

It’s still rough around the edges and doesn’t show every city, but it’s certainly an intriguing concept.

Check out the PlaneFinder 3D app.
