Looks like this site can filter by tail number. The two Shuttle Carrier Aircraft are N911NA and N905NA - not sure which one they're using for this particular flight. posted by backseatpilot at 7:53 AM on September 21, 2012
It looks like N905NA is being used for the Endeavour flight, but apparently tracking is not available. It's listed on FlightAware as NASA905. The latest track is from a few days ago, presumably when the plane flew from CA to FL to pick up the shuttle. posted by Nothlit at 7:59 AM on September 21, 2012
Cool thanks guys, it's supposed to take off around 8:15 or so, so hopefully one of these trackers kicks in at that point. posted by zeoslap at 8:12 AM on September 21, 2012
I think the tracks will not be available on FlightAware; I think the planes are blocked for privacy reasons.
The SF Chron has a detailed article with map on the flyover. It's in an hour, better hurry! Oakland airport should be amazing, and the SF waterfront flyby looks encouraging. posted by Nelson at 8:28 AM on September 21, 2012 [1 favorite]
