is critical to safe human spaceflight to mitigate the potential consequences of human error. “Manned commercial spaceflight is a new frontier, with many unknown risks and hazards. In such an environment, safety margins around known hazards must be rigorously established and, where possible, expanded. For commercial spaceflight to successfully mature, we must meticulously seek out and mitigate known hazards, as a prerequisite to identifying and mitigating new hazards.” In its submission to the NTSB, Virgin Galactic reports that the second SS2, currently nearing completion, has been modified with an automatic mechanical inhibit device to prevent locking or unlocking of the feather during safety-critical phases. An explicit warning about the dangers of premature unlocking has also been added to the checklist and operating handbook, and a formalized crew resource management (CRM) approach, already used by Virgin for its WK2 operations, is being adopted for SS2. However, despite CRM issues being cited as a likely contributing cause, Virgin confirmed that it would not modify the cockpit display system. While Virgin has been pursuing the development of a smallsat launch vehicle since 2012, the company began in 2015 to make the smallsat launch business a larger part of Virgin's core business plan, as the Virgin human spaceflight program has experienced multiple delays. This part of the business was spun off into a new company called Virgin Orbit in 2017. VSS Unity Following the crash of VSS Enterprise, the replacement SpaceShipTwo named VSS Unity was rolled out on 19 February 2016. Test flights were set to begin after ground tests completed in August 2016. VSS Unity completed its first flight, a successful glide test, in December 2016. The glide lasted ten minutes. By January 2018, seven glide tests had been completed, and on 5 April 2018 it performed a powered test flight, the first since 2014. By July 2018, Unity had gone considerably higher and faster in its testing program than had its predecessor. On 13 December 2018, VSS Unity reached a height of 82.7 km (51.4 miles) above the Earth at speeds close to three times the speed of sound. The two pilots, Mark "Forger" Stucky and Frederick "CJ" Sturckow earned commercial astronaut wings from the US government for the accomplishment. Another flight in February 2019 carried third crew member (1 in the passenger cabin) for the first time. After transfer to Spaceport America in New Mexico in February 2020, a couple of
