re: Wet blankets are not much fun, but...
The bigger question is the economics of it. It will probably do ok in the Asian market but will that be enough to carry it financially?
I really don't see many airports in the U.S. in the financial position to pay the $500 million or so needed for them to upgrade to handle it (modifying runways, taxi ways, gates...). And it was the lack of U.S. markets that killed the Concorde financially making it just a expensive show horse for Air France and British Air.
