I was here at work on the 2nd floor where we can see the whole horizon over the airport. I heard it leave but the clouds were so thick you couldnt even see it pop up from the tree line. Would have loved to know ahead of time so I could have taken an early lunch to get a little closer. I get regular emails form the FlightAware site but they've only created an iPhone app so far according to their site. Maybe some day down the road they'll create something for the android users who are also flight enthusiasts as well.
