Saw it too as I was driving south on 470 (around Jewel) at about 3:00pm. It was headed north (landing I think) and I swear it came to a dead stop in the air it was going so slow. My guess is it was 100ft up and a couple hundred feet to the West of 470 at the time. I didn't think any aircraft that size had any hover capabilities so I guess my eyes were playing tricks on me.

It was awesome to see.
