X-Plane 10.20+ XCOR Lynx MkIII. The XCOR Lynx is a suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. The Lynx is projected to carry one pilot, a ticketed passenger, and/or a payload or small satellites above 100 km altitude. This is an improved version of the Lynx MkI and II capable of transporting small satellites or a telescope in a pod on his back. By Vasco Ribeiro.
