As Randall Monroe from xkcd so accurately describes and explains using his drawings and tests inside of X-Plane (a flight simulator used by pilots with 20 years of engineering behind it) it’s rather difficult to fly a plane in on a planet with no environment. Not to mention temperature and pressure changes, along with gravitational pull. But the intriguing thing is that on Titan, a moon of Saturn, is better to fly in than on Earth: you could technically use a human glider, except that it’s really cold, at about 72 degrees Kelvin (-330.07 Fahrenheit). That’s really cold.
