A very old website where people can submit planes for the flight simulator X-Plane that are of absolutely low-quality. They also can surprisingly make money out of said planes.
Also it's a site still not affiliated with Laminar Research or Austin Meyer, creator of X-Plane.
Juan: Yo I just bought a new plane from X-Plane.org!
Pedro: Was it good?
Juan: Nah, it was absolutelygarbage.
Pedro: Leave a bad review on it then.
X-Plane 11 is another flight simulator. When FSX was running the flight simulator market, X-Plane launched an ultra realistic textured sim with particle physics. Addons were very expensive because making a plane was very difficult, while making planes in FSX was very easy. Prepar3d saw this and made a tweaked version of FSX with ultra realistic physics. So Prepar3d had the advantage of great physics and the simplicity of making addon aircraft. Although it is loved by the Aviation Community FS2020 is going to smash everything.
a planet that scientists hypothesize is found beyond pluto. we cannot see it due to our meek scientific technology. there are cosmic radiation signals or something being emitted that make other planets orbit right or something like that that pluto cannot cause, so therefore there must be another planet doing it.
