Boom's supersonic jet is facing a lack of interest from engine suppliers:

Boom recently lost its jet engine partner for the Overture supersonic jet, and other major engine manufacturers aren't interested in the project either, Insider has reported. After Boom signed an "engagement agreement" with Rolls-Royce for supersonic jet engines back in 2020, the latter announced last week that it had left the project. Now, other major jet engine manufacturers including Pratt & Whitney, GE Aviation, Honeywell and Safran Aircraft Engines have told FlightGlobal they're not currently interested in supersonic aircraft.

Boom said that the project is still on track, though, and that it will soon announce an engine partner. "We can reconfirm our intention to announce Boom's selected engine partner and transformational approach for reliable, cost-effective, and sustainable supersonic flight, later this year." Boom told Insider. The company has 20 airplanes on order from American Airlines and 15 from United. It plans to build build a factory in California and start flying passengers by 2029.

For its part, Rolls-Royce said that "after careful consideration... [we] have determined that the commercial aviation supersonic market is not currently a priority for us and, therefore, will not pursue further work on the program at this time."

    I didn't think they allowed supersonic flight at airshows. The deal where
    you can't hear them coming is apparent even at 0.9 mach. I think it can
    be attributed to the fact that even though they're not ahead of all the sound,
    they're ahead of a lot of it. The noise profile is higher behind the plane and there
    is a lot of din to cover the approach. I think they got startling crowds down to a science.

    Did you verify that the planes were supersonic? I know I've seen some videos
    where they broke the sound barrier for civilians, but it was on an aircraft carrier
    out at sea, and the civilians were wives, kids, etc. of active duty personnel I think.
    I never went on one of those.

    I think the last time I went to an airshow the F-18 was state of the art.
    I think all the F-fighters were equally impressive to me at the time. Seeing
    a cargo plane vault in to the air with JATO was trippy. I remember some of
    the static displays too. They had a crash simulator--a cockpit chair on an
    incline. So of course I was like, "Can I try that?". LOL, no. They just loaded
    uniformed volunteers in it once in a while, maybe every hour on the hour.

    I also saw a working oscilloscope there for the first time, and heard the
    phrase "avionics". No bones about it, they were there to make the military
    industrial complex look cool. Mission accomplished.

    Another memory that sticks out is that on the way there, we passed an Amish
    buggy. Even then I was struck by the contrast of that with what we were about
    to witness.

    In general though, the air shows were a bonding experience with my Dad.

    I'm sure you're correct- not past 1.0 mach. But had to be close- I remember there wasn't much din happening- something very low-key going on far out to the right and the F-14 came in from the left. There was no sound until it was overhead. Another time he came in from behind the crowd. Great memories.

    Long ago (~40 years) they were allowing us civilians to tour inside the planes. I remember a C-130. They had one of those ginormous C-5 there too with the cargo ramps open and you could walk through. At that same show they actually allowed people to sit in the cockpit of some kind of fighter. Well, somehow someone activated the ejection seat. I'm quite sure they died. I was there with some friends, one was a military officer. We heard a "boom" from far away, but I didn't think anything of it. Military officer ran off immediately. He knew that sound wasn't right.

    The Amish are interesting and most people don't understand them. Most people think the Amish are anti-technology, or something. Not so. You see them with cell phones, for example. And solar panels powering pumps and stuff on their farms. They'll have and use battery-powered tools. So what gives? It's mostly that they don't want to be dependent on "English" (that's what they call the rest of us) society. So that includes anything they can't grow or make on their own, so gasoline, natural gas, grid electricity, municipal water and sewer, etc. When I lived near some Amish areas I'd see them in regular grocery stores- well, locally-owned stores, not so much the major national chain stores. One time I was with a friend who was from Germany. The Amish will speak in their German dialect, unless "English" get too near. I was hoping my German friend could hear them and tell me if she could understand them, but they quickly switched back to English. I've worked on some jobsites (doing grunt work- wiring) where there were some Amish carpenters. Very hard workers, fast, and stunning beautiful work quality, including some pretty fancy intricate finish carpentry.

    I'm glad you went with your dad. I never did. There were many things I wanted to do with him but he's gone now, so I remember the things we did do.

    They don't go supersonic, but I've seen F35 on afterburners at dusk at Oshkosh doing aborted landing routine. No words can describe it.
