I think a lot of folks here want to protect Ukraine against a seriously evil Putin (hope we all see him the same). Hard to believe the UK, France, Germany, and Italy don't have the weapons, and perhaps the will? Perhaps, GDP and Industrial production are good measures....
Ignore context of what is said, ignore why those words were chosen, ignore motivation
"we are the thin blue line" -- This isn't okay. This isn't creating an inclusive environment. This isn't okay with the current political situation especially in the US. A maintainer speaking those words can't be kept. No matter how important or critical or relevant they are. They need to be removed until they learn. Learn what those words mean for a lot of marginalized people. Learn about what horrors it evokes in their minds.
You have to admire innovation. I'm in my 60s, remember the old sci-fi tv shows with rockets that would land on Earth by firing their engines. People used to laugh at that in the 70s and 80s when shuttle service was vogue. Hard to believe all the PhDs at NASA couldn't do the math on that, not to mention cost+ contracts would have made it amazing expensive.
You've go hand it to Space X and Musk for exploring and implementing new ideas.
