I'm not so sure about that.
In any event, spaceflight has to be taken out of the political sphere. Otherwise, you get what you see: NASA being used as a platform for all kinds of virtue-signaling and political agendas that have nothing to do with its original mission.
The private sector can take over now. This is the normal model. Government paid for the R&D for the first wide body jet (the C5-A), including for the TF39 high-bypass engine that powered it.
The technology then was transitioned to the private sector. The Boeing 747, Lockheed L-1011, and DC-10 followed, and the noisy TF39 was modified and improved to become the CF6 engine, from which modern high-bypass engine technology was derived. NASA has no large-scale mission at present. To continue to get its budget, it has to prostitute itself out to politicians.
Considering that the 747 first flew just a few months after the C5, don’t think you can really say that the 747 came from the C5.
And if I remember correctly, the AF liked Boeing’s bid better, but Lockheed was cheaper.
