It is great to see that Britain's Government sees this issue with a clarity that many in our own country do not. Bombardier wisely located some of its main production facilities for this program in the UK, anticipating it would need European support to enter this market.  It is encouraging to see that Boeing is very concerned with the economics of Bombardier's C-series aircraft program and a significant US market entry (Delta deal). The economics of the aircraft are very convincing, similar to what Boeing offers in the 787 category, where it is mopping the floor with Airbus, and this program could eat a significant bite out of the 737MAX market, which is a core Boeing product.
