Maybe ? the Sonic Cruiser will be launched in 2010 ? 2015 ?
I doubt it. The premium market for high speed is too small.
About a month ago i paid a visit to the Boeing website and their press releases indicate that they still itend to pursue the Sonic Cruiser. Boeing, unlike Airburst, conversed with airlines and airports in order to assess their existing infrastructure and needs and used that "grocery list" as the baseline for the SC. Imagine, asking the customer what they want and what they can handle before you design an aircraft.
Nope, Boeing won't make that, the airlines don't want it.
Gawd, hopefully the Sonic Cruiser will never be lauched. It is the absolute worst of both worlds: Fuel ineficent, yet not faster by enough to make it worthwile.
The speed gains over other long distance aircraft would amount to about a 15 minute savings at a 15% fuel penalty. You could eat up your 15 minutes of savings just waiting for your luggage at the baggage claim, because 3 A380s landed at the same time your plane did!
