  1. How the XB-1 #aircraft went supersonic without a #sonicboom
    In this case, the #BoomSupersonic #XB1 took advantage of a #physics phenomenon called the Mach cutoff. Because sound moves more slowly at higher altitudes, an aircraft breaching the sound barrier at those heights will produce a boom that cannot reach the ground – if the boom moves downward, the increasing speed of sound will deflect it, pushing its shock waves upward instead. newscientist.com/article/24677

  6. "Boomless Cruise: How Boom Supersonic’s XB-1 breaks the sound barrier quietly" by AeroTime - #XB1 test flight had sensors monitoring on the ground which confirmed no sonic boom reached the ground during three times it exceeded Mach 1. Using subsonic speed longer for climb, they reached Mach 1+ above the altitude where booms refract back up before reaching the ground. A nice new trick for potential #supersonic air #travel over land. aerotime.aero/articles/boom-su #aviation #avgeek

    Boom! We cracked it! Today we are introducing Boomless Cruise—supersonic flights up to 50% faster with no audible sonic boom.

    We quietly (har har) demo'd this on XB-1's first supersonic flight—three times actually. 🧵👇

  8. Weekly output: Boom Supersonic’s XB-1, Comcast low latency, painstaking passkey progress

    This has been a strange, sad and shocking week in the nation’s capital–first the mid-air collision outside National Airport Wednesday that left 67 people dead and ended a nearly 16-year streak without fatal crashes by U.S. airlines, then Elon Musk’s attempts to stage what I have to call a digital coup at the Treasury Department and the Agency for International Development.

    Patreon readers got an extra post this week: my annual breakdown of last year’s income according to the business models of my freelance clients.

    1/28/2025: Boom Supersonic’s XB-1 Testbed Plane Breaks the Sound Barrier, PCMag

    Having Boom bump this test flight from Monday to Tuesday gave me a little extra time to check two descriptions of the XB-1: “independently developed” (Boom did this without government dollars or direction, unlike the Northrop F-20 fighter that was built with private money but was based on the earlier, taxpayer-funded F-5, and which that company developed at the request of the Pentagon) and “exceed Mach 1” (XB-1 sustained that achievement in level flight, unlike the Bombardier business-jet prototype that cracked the sound barrier in shallow dives in 2021).

    Comcast’s announcement of this new feature was shockingly short on details, but a company publicist was willing to answer e-mail after e-mail as I realized the data points I needed to write this post.

    2/1/2025: The Passkey Future Is Here, But Some Companies Still Make It Too Complicated, PCMag

    A year after I interviewed FIDO Alliance CEO Andrew Shikiar at a conference in D.C. about identity and authentication, I sat down with him at the 2025 version of this conference to discuss what the industry had and had not accomplished since January.

    I’ve been following “Boom Supersonic” and “Tokamak Energy” on the internet for years now, and it’s great to see the breakthrough from Boom today. Hopefully Overture will be a lot nearer, and supersonic passenger flights will soon be flying again!
