When I was young
We could fly to the Moon, design a reusable space ship and fly to New York before lunch.
The Shuttle turned out to be a horribly flawed design, but my god the ambition it represented. If you ever get a chance go and take a look at a Space Shuttle main engine - it is a work of genius and an absolute triumph of engineering. It has to survive the temperature of liquid hydrogen without shattering like glass or developing leaks; the heat of an oxy-hydrogen flame without turning into a puddle, it has to pump biblical amounts of liquid without bubbling or variation. And then it has to get through the incredible vibration of takeoff and acceleration, moving and throttling throughout, return to Earth - and then do it again and again.
