What i was pointing out primarly is that the A350 will probably get government support so if things cock up Airbus dont loose out. I'll reming you the MD-11 had a lot of orders before it flew.
And yet... the 737-200, 757, A320 all had relativly slow starts, only to pick-up rapidly later in life. The 777 also took 4 years to sell 100 copies. The inital sales years (and today the 7E7 stands at exactly 1 year ATO) are almost meaningless to the life of the aircraft...
The replacement market for 767s at UA
alone are enough to reach Boeing's break even goal of roughly 500 units.....
