Actually, methinks this is dejavu all over again for Bombardier...anybody else remember the BRJ-X? Thiswas their 'big' RJ program before the C-series which got 'postponed' until everybody forgot about it... then a few years after that along comes the C (too little too late) series.
It seems to me that the boys from Brazil have got this segment sewn up(which they have ever since the 728/928 bit the dust). Can't see the punters going for a 900 stretch when there are all those 'big' aeroplane 190 and 195s around.
Interesting that they are looking at a Q400 stretch (Q500?) that's going to be one lonnnngggg puppy. Any Q4 drivers care to comment on a 10 foot extentsion?
That said the Q400 is the only product in the portfolio that has had a production rate increase in recent years so maybe there is some mileage in that idea let's hear it for props!
