I don't think I'm giving away the store when if I tell you that Douglas and Boeing are working together on the HSCT even as we speak. It was all over the local papers, and I know the fellow who is doing the coordination. Heck, I even know the guy doing the digital inboard profile. :-) I agree with Karl's analysis of the market forces for this airplane. I would also add that the business traveler is usually willing to pay more for reduced flight time because time really can be money for that class of passenger. Hence ticket price can creep up just a bit to cover what are obviously higher operating costs. >One key feature of any such plane is sufficient range to fly Tokyo- >New York non-stop, keeping in mind that the distance may be greater >than for a sub-sonic aircraft because of the need to avoid flying >over land areas.

The other big scenario (and my information is a couple of years old here) is to start with a West Coast US to Tokyo range, and grow into the New York to Tokyo market after a couple of years, ala 'B' Market 777. Another variable here is sonic boom reduction technology. With some advances that don't require weird configuration compromises we could conceivably see overland SST flight, and not just in Siberia. >Another consideration is capacity.

There undoubtedly are some substantial tech- >nical hurdles to clear first, however. It has been awhile, but I think the Boeing HSCT has a 325 seat count. In a three class layout, of course. :-) The technical hurdles for this class of airplane, and not just the Boeing version are materials and engines. The current class of materials certified for aerospace structural application tend to creep under the high temperatures associated with Mach 2+ flight. This is not good. :-) Engines need to be very quiet on takeoff and approach, yet be very efficient at 50,000+ ft and Mach 2 or faster. Not to mention they need to be utterly reliable, and if one *does* have the poor manners to fail en route, the other engines must have the efficiency to get to a suitable airport while flying off-design. Pretty stiff set of requirements at the moment. >It's worth noting that the Pacific Rim market is also the turf of >the 650-seat aircraft proposals floating around.

Hey, don't be knocking my airplane! It pays the bills around here. :-) I would also like to point out that even if the HSCT comes on line as predicted, it will have nowhere near the economics of the NLA (600 seats). And if you are going on vacation, you aren't nearly so concerned with flight time as price. And the NLA will have it all over the HSCT in terms of operating cost. I would guess that one could purchase a ticket to Tokyo from San Francisco on an NLA for only 2/3 of what you would pay for that ticket on an HSCT - and that is assuming that everyone meets their economic targets. Not that I'm against the HSCT. I think it is an obvious area for growth.
