Through August 16, Boeing’s backlog of orders totaled 5,697 commercial jets, of which 4,404 are orders for the 737. The 777 backlog is 476, including both the Classic and the 777X, of which just 170 are orders for the Classic. At a production rate of seven per month that backlog will last two years, but that leaves Boeing with no backlog until the 777X is in production. The company has admitted it needs 40 to 50 new orders per year for the 777 in order to bridge the production gap between the new and old versions of the plane. So far this year it has taken eight new orders.
