This has nothing to do with a software engineer looking down on other types of engineering, since I'm not a software engineer. My post was all about Boom's marketing mouth making claims that it won't be able to back up, or possibly making half-truths that are going to leave people disappointed.

I'm also an "aerospace veteran" and have seen more projects cancelled than succeed (most recently the Lear 85). Designing a new plane is capital "H" Hard. That goes doubly so for planes that are big departures from the previous experience of the company. Cessna makes great light business jets. They are currently trying to design a line of bigger jets and are finding it very hard. Lear can't figure out how to make anything without mechanical flight controls. It takes a couple generations of design to figure things out. So a bunch of engineers from Scaled and Boeing aren't going to help. How many ex-Concorde engineers have they hired?
