The record flight, which is supposed to take place either in April or else after October this year, is expected to begin somewhere within the continental United States, possibly in Ohio, land of the Wright brothers. A long runway is needed; in fact, rocket assist was considered for the F-109 engined version, and then (at least provisionally) discarded for the more powerful FJ44. Laden with 18,000 pounds of fuel, indicating a constant 100 knots, the airplane will climb gradually to an eventual cruising altitude of 45,000 feet. There it will maintain a speed of .4 Mach-not the most efficient speed aerodynamically as the airplane gets lighter, but one required to keep the engine happy at that altitude. With an expected tailwind of 60 knots or so-much more if Fossett can locate and hitch a ride on the jetstream-the gangly jet should make it around the planet in something between 60 and 80 hours before alighting, with twin drag chutes billowing, at the airport from which it departed.
