    SR-71 was most economical when it "cruised" at M3 !!!

    You can only go supersonic over water - so...

    Usefulness severely impacted for a commercial client...

    With what stops along the way, Seattle to Japan is 4800mi, an f4 best cruise (subsonic) would make 2600...

    What else is supersonic and buyable?

    Yes, but required a refueling because it’s range of 3000 miles was still not long enough for supersonic sea routes.

    Technically you could use it to run up and down the coasts and have about 40,000-50,000lbs of cargo or passengers instead of fuel. But that would still be like $5000-10,000 per seat.

    Dassault has a lot of good fighters that could supercruise when “naked”, and with a modern engine like an F-119 they could probably go 1000 miles like that.

    They had the Mirage IV bomber that held the 1000km speed record before the SR-71, which was one of the main inspirations for the Concorde. It’s basically a baby Concorde. With a modern engine it would have absolutely been capable of over 1000 miles supersonic. Maybe closer to 1500 at 1.5 or 1.6.

    No, your eyes do not deceive you.

    It’s called the Aerion AS2.

    I only added the name instead of a link because the articles are all piecemeal and don’t really tell the whole story by themselves.

    But Wikipedia has a decent collection of information from across various sources.

    Here is a good ride: https://en.wikipedia.org/wiki/North_American_X-15

    World's first man carrying space ship.

    Scott Crossfield could have become the first astronaut in the world..had he decided to be one.

    This pretty much describes the million dollar hamburger I have been craving. I think I would take the kids along though. It would be worth missing a day of school; or perhaps we could do it next Saturday and stay over to Sunday evening.

    From https://boomsupersonic.com/travel

    Imagine crossing the Atlantic, conducting business, and being home in time to tuck your kids into bed. Leave DC at 6:00am and make a 3:30pm meeting in central London. Take your clients out to dinner and still be back in DC by 7:30pm local.

    Not many jets can fly rhe atlantic without refuelling. A 104 certainly couldn't. Very few could fly it supersonic. I can only think of two, perhaps three.

    Didn't Burt just test that a carbon fibre space plane can reach the space and land safely ?

    Twice. The first time was SpaceShipOne way back in 2004. The recent test was SpaceShipTwo, which is far more advanced and can carry passengers as well.

    So it’s quite well proven now.

    Very well then...wouldn't everyone like to go to space enroute to somewhere far over the ocean...at least once in their lifetime ?

    There is a big difference between straight up and down verses into space, go somewhere, then reenter the atmosphere.

    Yes there is...but wasn't Burt able to do his stunt with just "pocket money" ?

    Yeah, maybe to Paul Allen it was just pocket money. Although Rutan points out that Allen is the only space entrepreneur who turned a profit.

    I dunno, SpaceX has done pretty good so far. I believe the new starship is the first model that required outside investment, which was provided by a Japanese billionaire who wants to be the first tourist to orbit the moon.
