It's not like GE and P&W are bad choices given the fact that they made some of the best military jet engines in this world. While comparing fighter jet with large aircraft might not be fair, I think B-1B Lancer will be a good analogy in this case (similar size, 4-engine layout, and twice the takeoff weight). And B-1B Lancer use engines from GE.

They're not bad choices at all, and I'm sure Boom would love to work with either of them. But the question is whether or not GE or P&W are interested in working with this vaporware company.

I have recently toured the GE plants where the engines are assembled and developed. I have worked in the same office with the engineers who design and service the engines. No way in hell GE can do this given the amount of resources for this project. And I highly doubt Boom would like working with them at all.

GE gets skittish about a project when the government has already given them billions to develop it.
