- d0mine 18y agoApparently, the brothers had just recorded evidence that a manned Soviet spacecraft somehow got off course and left Earth's orbit, permanently. </quote> This single sentence is enough to discredit the whole story. It is technically impossible for manned spacecraft to leave Earth's gravity by accident.
- pc 18y agoIt's unlikely, but far from impossible. The delta v to get to low-earth orbit is about 10 km/s (more depending on drag), while the delta vs from low earth orbit to the Lagrangian points, low lunar orbit, or even earth escape velocity are of the order of just 3-4 km/s.
