FIRST CUSTOMER ECLIPSE 500 DELIVERED
Eclipse delivered its first customer aircraft December
31, at its headquarters in Albuquerque, New Mexico. Ramping
up to fulfill the backlog of more than 2,500 aircraft, the
company already has 37 additional aircraft on its production
line in various stages of assembly. Seven of these aircraft
have completed final assembly and are being prepared for
delivery.

Well, that should satisfy the skeptics as to whether the E500 is a viable
product. I'll bet Cessna wished they had a 2,500 plane backlog on any of
their models (and perhaps their entire line).
