1960's: Car vs. Jet Pack

The best line about this thing is the part where the narrator says "all you need a few hundred gallons of liquid hydrogen." We all know how easy that is to obtain. I love the idea of using a jet propulsion system on the moon. Can you imagine the amount of moon dust? Also, with your jet pack man accustomed to Earth's gravity, isn't there a good chance that this guy squeezes a bit too much power and flies away from the moon? I guess that is how you come to the right answer, by getting it wrong a number of times.
