100 years of space flight?
If you count Sputnik it is 56 years. If you count the V1, it’s 70 years.
If you count Robert Goddard, it’s about 100 years.
Goddard only got up to about two miles in altitude, but he did it with a liquid-fueled engine.
Too bad he didn’t like math, or he might have figured out how to scale his combustion chambers up without melting them. Of course, he wouldn’t have had access to high-speed turbopumps even if he had figured out regenerative cooling.
That’s why I said “almost.” An even 100 years makes the joke much funnier, you see
