Smaller business class Jets?
Britain, and France lead the way with the one-hundred seat Concorde until a crash in France twenty-five years ago ended a most successful trans-Atlantic affair, meanwhile only Singapore airlines operated the type and the Soviet-Russians operated their Tupolev TU-144 between Moscow and the far east, but the demand was not strong and the type was retired too!
On the other hand the U.S. has gone it alone with several larger Boeing concepts, but this new type will allow a one third version to be built more so for private and business flights and to be employed world wide, the secret to this type is perhaps alternative fuel, speed and operational costs being much lower than the original types?
One will just have to wait and see what will happen, or is this another red herring, pink elephants ect, that we will never see the light of day as so many went before!
