   My earlier posting had my back-of-the-envelope calculations showing
that a flat pressure cabin for a blended-body airliner is quite practical
and can be designed as a set of intersecting cylinders. As should be
expected, a real aeronautical engineer can do better than I can. In the
book "Shorts Aircraft since 1900" by C.H. Barnes I came across a picture
of a proposed flying wing airliner designed by Geoffrey Hill. He used a
"quilted" pressure cabin made up of intersecting spheres. The tension
links needed to hold the shape are then slim pillars set in a square array
with about fifteen or twenty feet between pillars, with the arched ceiling
between pillars giving a very spacious look to the cabin.
   The design was called the Pterodactly VIII and was submitted to the
Brabazon Commission. It had five Rolls Royce Griffen engines with pusher
props, and would seem to be made to the same specifications as the Bristol
   In a large blended-body airliner the average seat will not be as near a
window as on conventional planes, to the extent that this is a problem.
Each passenger could have a video display screen that could give an
outside view as well as being used for entertainment and preflight safety
briefings. I have read that it is or will soon be possible to combine the
views of several digital television cameras onto a screen. This might
allow the plane to have a set of external view cameras giving 360 degree
coverage, and each passenger could look in any desired direction by
combining the signals in their screen.
