Boeing Reach Its 787 50-50 Benchmark

The 50-50 benchmark is a point where the same number of 787 delivered equals its reported backlog as shown below:

This is a significant milestone for Boeings' 787 programs. More orders are being booked at this time so the 50-50 relationship will drop back closer to a 48-52 relationship unless orders are held for the Farnborough  Airshow, then it remains close to 50-50 book to bill ratio (backlog to delivery ratio) or the perfect "one" most manufacturers seek.
