Declining sales is not to be blamed on unfair competition, but rather, in my opinion, on management that has failed to reinvest in R&D and new product development. While Airbus’ 10 or so current models all have the same type rating, have extensive design commonalities, and are all based only two different fuselage cross-sections, Boeing’s line-up was as of two years ago a hodge-podge of 6 mostly different products, mostly poorly integrated, and, as mentioned, averaging 20 or more years of age. Preach it from the mountain, brother! About time someone calls Boeing (or really, the old McDonnell-Douglas management) to account for it's missteps. The "EU subsidy" argument is getting tiresome.
The real crime is in the regional jet market. Embraer, Canadair, Dornier. Not a damn one made in the USA. How in the heck could our aviation industry so totally misread the demand??
