Despite “challenges” in assembly of the first Boeing 787 prototype that have forced delay of the first flight and certification by at least six months, Boeing Business Jets does not expect the delay to have any impact on delivery dates for executive models of the new jetliner. As of today, Boeing claims to have firm orders for nine executive 787s–five 787-8s and four 787-9s. Two of the nine will go to an unidentified leasing company. According to Boeing Business Jets president Steven Hill, the first green airplane is scheduled for delivery to an independent completion center for outfitting in May 2010. The next available slot is in early 2016. Hill has described the 787 as “the next, probably the greatest, VIP aircraft derived from an airliner.” It will offer a max cabin altitude of 6,000 feet, improved air purification system, a cruise speed of Mach 0.85 and range of about 8,000 nm.
