Given the significant amount of re-engineering on the 737, for a relatively short lifespan, I would suspect the 737RE to be a loss for Boeing.
They had resisted this to-date for a reason....
just as the tanker deal was a last ditch effort to win at all costs, losing already a $billion on the first 4 aircraft...
this RE appears much the same deal.
How is the 786 coming along?
786??
