How does the Pseudo-Satellite Zephyr land?
After some power googling...

  Launch and recovery The air vehicle is launched by hand. Recovery is
  by belly landing as the air vehicle has neither landing gear nor
  landing parachutes.

  It is hand-launched by a five-man ground crew, and recovered by belly-landing.

  Launch: hand launch Recovery: autonomous belly landing


It has two-bladed props, so they can be positioned to avoid a ground strike.
