Three hours in

I've just been to the last press conference of the day, three hours into the flight. So far it's all gone very smoothly: no word on whether Fossett's had a milkshake yet, but he has covered 869 miles and reached an altitude of 38,000ft over Detroit.

I am going to do a final update of my story, to go up on the site when the early shift arrives, and go to bed. I've been up since 4.30am and, unlike Steve, I have no intention of staying awake for 80 hours.
