A cessna would need wings as large as a 747 and be traveling about mach 1 to take off, iirc.

So it would need wings that have ten? times more surface... that doesn't mean this couldn't be done using small scale drone designs.

Mach 1 always means the speed of sound in the local environment.

On Mars. Mach, the speed of sound (vibrations), varies with changes in heat, density, etc.
