I know that many aerospace engineers were skeptical it would be possible to achieve ignition when facing "backwards" during hypersonic flight. No way to get the right mixture in exhaust chamber.

Even engines that "startup" more than once were pretty "out there". Over the years watching along, I've gotten the feeling that getting the engines to restart at all, and then restart in the right order and with enough consistency was one of the major breakthroughs.

I found the NASA blog entry on engine ignition pretty interesting (https://blogs.nasa.gov/J2X/tag/ignition/). Doing that when you have mach 6 winds blowing always seems amazing to me.
