I would speculate that it lands on skids. Skids are pretty lightweight and will do fine for landing, but you need a lot of power to take off with them unless you're on ice or snow.

(You know your landing gear is up when it takes full power to taxi.)

good call. The U2 has only gears in the center and "skids" on the wings, trying to get as slow as possible before they are needed (an some muscle car following for guidance). https://youtu.be/hxFz6ImB8fI?t=165

A lot of gliders do this and are designed for grass/turf airstrips.
