If they hired a propulsion guy from Boeing to develop a new super-sonic engine, Boom fucked up. Boeing, same for Airbus, doesn't develop or built engines, let alone super sonic ones.

But dor sure, said Boeing hire will be royaly paid for his service, good for them. And good for Boom, a prominent Boeing hire will make fundraising so much easier.

But sure, as if building a new commercial airframe manufacturer isn't hard enough, becoming a new jet engine manufacturer on top of that is a winning strategy...

In the specific case of Mr. Powell, I would agree that his skill set is primarily in the management of procuring and integrating of new engines from engine vendors into new airframes, and in the detail design of engine accessories and externals, and he is not experienced in the design of internal turbo machinery. And that's where the high risk for Boom is.

However you would be completely mistaken to think that Boeing, and Airbus, and my friends down there with Embraer, do not have people who actively pursue and develop the core technologies needed to develop, analyze, and test all types of turbine engines, even if they do not result in market products. It is a necessary tool in order to evaluate offerings from the different competitive engine vendors. And at the senior level of engineering, there is basically a revolving door between the airframe manufacturers, the engine manufacturers, and a few of the high-level engineering focused airlines. People are constantly jumping around between them, there is a lot of cross-pollination going on.

Yeah, I know some of those engineering managers. They all work best in well-established, large orgs with people knowing the ins and outs of their jobs.

The last time they actually developed something is quite a while ago. And managing engine suppliers, and component suppliers only gets you so far in developing the engines yourself. And we are talking super sonics ones.

Designing airframes isn't easy but aren't really novel. This is about coming up with engines that don't have noise concerns and have economics that would allow airlines to operate aircraft at prices that aren't that out of line with current ticket prices. It's not at all clear how big the market is for very premium tickets for supersonic travel is transatlantic and transpacific has a bunch of other range issues.

Conventional airframes are not novel, building an aircraft is still incredibly hard so.

Civilian super sonic airframes so are novel, nobody did that since the days of the Concord and its Tupolev clone.
