> Boom promises... ultra-wealthy people a few hours shorter flights?

The question I was replying to is not whether they can build a profitable business, but whether they can build their own engine within 5 years.

There's a greater than zero percent chance they can do this if they put in the focus and the effort.

There's also a greater than zero percent chance that they can build a successful engine and then still go bankrupt.

Early SpaceX had funding issues and likely would've gone bankrupt if the 4th launch of the Falcon 1 didn't succeed (the first 3 all failed).

So good luck to Boom. Even if they don't succeed, I'm glad they are going to try.
