BTW a quick look at biz jets shows only the Embraer Lineage and Boeing and Airbus models have room for more than 10 passengers. Everything else is 10 or less. So in addition to being a FOAK passenger carrying M5 aircraft it is also a large FOAK aircraft in its class.
Umm, no. There are plenty of business jets that can accommodate more than that. The thing with business jets, particularly the larger ones, is that what they can accommodate, and what they are actually equipped for, are often pretty different, especially as you get into the larger sizes. If you come across a bizliner (one of those Boeing/Airbus ones, or the E-170/E-190 derivative Embraers) that's truly only equipped for 19 passengers, you're looking at separate full-size bedrooms, showers, and a lot of open floor space.
Someone mentioned 19 is the magic number so TSA doesn't require fancy inspections?
Hermeus got some kind of SBIR grant for some of their earlier work. Some time in the last 1-2 years I think. I wonder what the best way to look for what their submission would be? Company name? Principle investigators? [EDITHad a bit of a nose around the SBIR database and found this and thisIn contrast the Hermeus founders only show up on some awards for general hypersonic design study work. It looks like the key stuff is (or was) being done by "Advanced Cooling Technologies" PA for precooler design, who were going to license the tech to GoHYpersonic. May have done so. I'm not sure if there's a delay on releasing current year SBIR reports but I don't think so. I think REL might have a case for patent infringement based on the description of the precooler work as well. ]
Most of patents REL had were around frost control on designs which they aren't actually using anymore as they aren't liquifying the air anymore.
Came across an interesting interview with Gene Holloway of Aerion talking about biz jets, their supersonic plane, sonic booms over land and how they plan to deal with it. Dynamically modelling the atmosphere in front and using inversion layers to reflect the boom is something I've not heard of before..https://newatlas.com/aircraft/aerion-interview-as2-supersonic-business-jet/
The tail number N60304 is not assigned. A test vehicle would need a tail number registered with the FAA. Must be a mockup or something put together to impress the investors.

I have a tail number reserved for my airplane but haven't yet registered it as I'm not done building it yet.
While this Quarterhorse prototype was not designed to fly, it is much more than just a showpiece. Building this vehicle was an exercise in multidisciplinary design, manufacturing, and the integration of complete systems.

No shock diamonds? Didn't look too tied down either.
