I just spent half an hour arguing with my father about how Superman flies.
"Superman doesn't fly."
"Yes, he does."
"No, he just jumps really high, and then uses his muscles to stay in the air."
"That doesn't make any sense!"
"It's like swimming. You can change direction in the water, right?"
"By pushing against the water. Superman couldn't push hard enough against the air without causing storms."
"Parachutists can change direction in the air by moving their muscles."
"They can't go *up*. Or change direction in *space*."
"Space isn't a true vacuum! There are still tiny particles."
"Then we'd *see* him doggy-paddling to Saturn. Which he doesn't."
"You need to open your mind!"
"You need to take a physics class!"
For the record: when under a yellow sun, Superman can manipulate his own personal gravitational field, and THAT'S how he flies.
Anything else is SILLY!

Although it seems he lived in the times before *physics* was invented...
