   I have questions for the proponents of a commercial flying wing.
Could this ship use existing airport facilities and runways? How hard
would be to adapt present infrastructure? And after all, what are
the dimensions of a flying wing with the same cargo/pax/range
capabilities of current airliners, like a 767-300 or a 747-400?
I'm thinking you guys are spending too much time in the
wind tunnel.
Given the projected growth in passenger trips, the fact that the
world population will stop growing, and that each one of us can only do
up to a given amount of travel (some cannot do any because
they are scared of flying), the size of the largest aircraft
available to airlines will converge to a given number.
On top of that, the original posting already mentioned that the
economies of scale for aircraft large than the 747 may not exist.
There would be no incentive to pack 800 people together if it costs
the same to pack them in two 400-people sets. And the latter is becoming
more and more a much better marketing proposition.
Scenario: Boeing launches a stretched 777-400 and drops the 747
for good.
