Virgin Galactic pilots Mark “Forger” Stucky and Frederick “C.J.” Sturckow, who were awarded civilian astronaut wings last week, are among 18 pilots who have flown suborbital flights.
The two pilots flew SpaceShipTwo Unity to an altitude of 51.4 miles (82.72 km) on Dec. 13, 2018. That accomplishment qualified them for civilian astronaut wings using an American definition that places the boundary of space at 50 miles (80.46 km).
Some day, Richard Branson might fly to space, gaze out the window, and see stars with his naked eyes, unencumbered by the Earth’s atmosphere or the optics of a telescope.
For the moment, he has to settle for his own fame and a star encased in concrete along the Hollywood Walk of Fame.
The British billionaire was in Los Angeles last month for the unveiling of his star on that famous boulevard. While he was in the neighborhood, he popped up to the Mojave Air and Space Port, where Virgin Galactic and The Spaceship Company are working to make his dream of spaceflight a reality.
Given his early October prediction that Virgin Galactic’s SpaceShipTwo Unity would fly to space in “weeks, not months,” one might have expected him to be here to view a spaceflight he has been promising for the past 14 years.
With Richard Branson once again predicting that Virgin Galactic will fly SpaeShipTwo into space before the end of the year, it seems like a good time to take a look at the history of suborbital spaceflight.
The number of manned suborbital flights varies depending upon the definition you use. The internationally recognized boundary is 100 km (62.1 miles), which is also known as the Karman line. The U.S. Air Force awarded astronaut wings to any pilot who exceeded 80.5 km (50 miles).
