Some of these airplanes are built especially for this sort of thing. The airplane landing has full length flaps, not too common in lightplanes. Also, note the big tundra wheels on some of them, for landing on soft ground (and beaches). The STOL qualities depend on what the wind speed is too. In a good stiff breeze, a J-3 Cub can hover in the air with no forward movement.
Doing that have caused little old ladies to call the police, and asking “Would someone please go up and rescue that pilot? He’s stalled his airplane and can’t move!” Just how the police were expected to get up to him is another question!
