> This is true for all pioneers He wasn't a pioneer, though. It's one thing when people say it can't be physically done, and the people talking have no theoretical basis to support it. People said it would never be possible to fly, but they has zero physics to back up the statement. It's another when it has been physically done and the physics behind it is well understood. If he believe he was building a faster than engine using some new gravmetric-eletromagnetic effect, well more power to him. We have an ample amount of history on rockets, how to compute the physical performance of them, and a multitude of failure scenarios. This was ignored. When it came to putting a man on the moon, we used the might of our education to predict everything we could and used hindsight when we failed. Importantly, we built into the systems things that would tell us what was happening so if there was a failure we could learn to not make the same mistake again. Rocket systems fail, which is why you launch them without people first.
