Answer: Not greatest "time"
The FAA regulation says that minimum of 45 min flight fuel should be reserved. Since the GlobalFlyer can have limited fuel quantity and will have only 5 % left when he lands at Salina, he cannot extend the distance more.
K-State at Salina students tracked the progress of aviator Steve Fossett as he successfully piloted the Virgin Atlantic GlobalFlyer around the world in pursuit of the Closed Circuit Distance Record. For more information go to www.salina.k-state.edu/globalflyer
