It is possible. Read "The Menace From Earth". Heinlein always did a lot of calculations, like calculating Geostationary Orbit before such things were common knowledge.
On the moon, a man weighs about 1/6th on earth. Now have a very large cavern used as air storage, at 2 atmospheres, and humans might be able to fly.
