      I wonder what mineral the craft consists of. Light speed, heat/fire proof? Learn to intercept their radioes/radar? They know how to jam our radars. Think Amelia Earhart. 🐣 #calcium #coralisland #pyramidsofgiza #limestone #calciumisthefuture

                                                      Ik its a joke but Steven made a good point by accident, if we can calculate its following gravity, they could have workwd out a route based on the gravity to preserve fuel and that could be a mode of space travel so ik it was silly but it would work..
