n(Sub-orbital means that he did not reach the speed – around 17,600 mph – necessary to get into orbit. Also, a sub-orbital spaceflight has an apogee – the highest point of its trajectory – that reaches “outer space,” around 100 km or 62 miles, but its perigee – the closest point to Earth – does not. Obviously, since the spaceship actually returns to Earth, making its perigee zero, right?)
