they flout in the air
An airship is a lighter-than-air aircraft which can be propelled forward through the air as well as steered.
An airship uses helium which weighs less than air, and it cancels out the weight of the airship. Hydrogen weighs even less than helium, but it is combustible, so helium is preferred for use in airships.

No, the Montgoflier brothers flew a hot air balloon, radically different from an airship.
The air around the airship has gravitational potential energy as well. When the airship rises, this air is able to go down to occupy the space the airship formally took up.
A hot air balloon is powerless, relying on the winds for locomotion, while an airship has a motor, allowing it to drift with its own power.

As a verb: She would not only flout the rules, she would flout those who did follow them. As a noun: That flout is an improper way to speak to a teacher.
A hot air balloon does not have any mean of steering and does not have permanent flotation. An airship has a permanent means of flotation (lighter than air gas bags) and a means of propulsion.
An aeronaut is a person who glides through the air in an airship or balloon.
