Note that Boeing 787 has not flown, although it was "rolled out" before Superjet.
How long before Superjet is in service? Is March 2009 a realistic flight test goal? (Superjet is applying for FAA and JAA certifications, but neither of them is needed for EIS because the launch customer is Aeroflot who can fly the plane under Russian certification before the others are issued.)
