    This is kind of interesting. Could save the domestic airlines some fuel (probably) if they implemented it on normal jets too. But since (unlike with cameras) airline windows mostly provide an esthetic view, people might object to this.

    the idea has been talked about for years. passengers don't want it.

    you could also extend that concept to houses.by having lcd displays
    that show the outside rather than windows, you could better insulate
    the house, reducing heating and cooling costs. nobody would want that
    either.

    Horrible idea. I can't believe anyone would want this other than
    greedy airlines.

    Supersonic aircraft skins stretch due to heating at high speed - the
    longer the fuselage the more stretch. The cabin shell does not. On the
    Concorde passengers would see the offset between the cabin window and
    the fuselage window. It was significant. OTOH, at 60,000 feet altitude
    there isn't much to see in any case.

    It could be that the proposed aircraft has a composite fuselage and
    while I don't know the stretch characteristics of that with heating,
    there still remains drag.

    Parasitic drag grows as a square of the speed so they have to look for
    every opportunity to eliminate it. "Little things" like many window
    seams mean a lot of drag. A smoother fuselage is a good thing.

    Looking at the sketch of the aircraft, area rule is obeyed very far back
    on the aircraft where the wing is. That makes for a nice uniform cabin
    shape ... but it looks to me like the cg is much further forward than
    cL. Doesn't make sense unless there is a retractable canard for t/o and
    landing and that the body provides compensating lift in cruise...
    (speculation only).

    The engines in close proximity defy current certification dogma (er,
    rules) - I suppose they could put in a titanium/composite sandwich for
    catastrophic events.

    That said, I doubt very much that such an airliner will ever come to the
    market.

    It's a bizjet. "Greedy airlines" are not involved.

    If we did, we could live in burrows, like rabbits or prairie dogs.

    We do now, except that we build them above ground.

    People who want to reduce fuel burn/greenhouses gases might like the
    idea too.

    Yes, but the people riding these planes will be forking over $15,000/each for things like a one-way ticket from New York to London. They are different.
