On Titan the atmosphere is so thick and the gravity so low that humans could fly through it by flapping “wings” attached to their arms

Titan is one of the moons on Planet Saturn. It is said that here, the atmosphere is so thick and the gravity so low that you could fly through it like a bird does on Earth by flapping wings attached to your arms. This statement can be found in the book Entering Space: Creating a Spacefaring Civilization by Robert Zubrin.

Of course, the atmosphere on Titan would not be conducive for your health, so a spacesuit could come in handy. The Voyager has been able to make some observations that prove the atmosphere on Titan is denser than Earth’s, and this has been put at about 1.19 times as immense as Earth’s overall.

The lower gravity on Titan implies that the atmosphere extends way much more than Earth’s. This was even proven by the Cassini spacecraft that flying at a distance of 975 km, had to make adjustments to maintain a steady orbit against atmospheric drag.
