Virgin Galactic Unity 22 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which launched on 11 July 2021.[1] The crew consisted of pilots David Mackay and Michael Masucci as well as passengers Sirisha Bandla, Colin Bennett, Beth Moses, and Richard Branson.[2]
Background
On 7 June 2021, Jeff Bezos announced that he planned to be on the first crewed flight of his company Blue Origin, which meant being aboard the first crewed flight to space (suborbital) of a private enterprise fully funded by private money.[3] In the following days, rumors began to spread that Richard Branson was filing paperwork to make a similar suborbital flight as part of his own private enterprise, beating Bezos to claim such a first achievement.
There has been debate whether Virgin Galactic, which gets close to, but does not reach, the Kármán line, would in fact be achieving such a first commercial private flight to space.[4] The United States and NASA defines the border of space to be 80 km (50 miles) above Earth (which is approximately the minimum possible altitude a satellite on a highly elliptical Earth orbit can reach and sustain its velocity). All other spacefaring countries and the FAI define outer space as above the Kármán line at 100 kilometres (62 mi).
Despite the rivalry (dubbed the "billionaire space race"), shortly before the flight, Bezos offered well wishes to Branson.[5] SpaceX founder and chief executive officer Elon Musk met with Branson shortly before the flight.[6]

Flight
On 11 July 2021, Unity's mother ship VMS Eve carried VSS Unity in a parasite configuration to be drop launched. During ascent a red warning light indicated a deviation from the ship's entry glide cone, but the flight was able to proceed and land successfully regardless. [7] At T+2:38, Unity reached apogee at a 282,773 ft (86,189 m) altitude (below the FAI's space boundary, the Kármán line's upper border at 100 km (62 mi) altitude, but above the United States' space boundary at 80 km (50 mi) and just above the mesopause at 86.182 km (53.551 mi).[8][9]
Due to the entry glide cone deviation and a departure from the planned route, the flight would later come under investigation by the Federal Aviation Administration. Virgin Galactic disputed the safety impact of the deviation, and noted they were cooperating with the FAA in the investigation, in a public statement.[10] On September 2, 2021 it was publicly announced that SpaceShipTwo would be grounded by FAA order until the investigation into the flight deviance was complete.[11] Former Virgin Galactic test pilot Mark P. Stucky would publicly call out on Twitter the flight deviation and Virgin Galactic's response by saying: "The most misleading statement today was Virgin Galactic's. The facts are the pilots failed to trim to achieve the proper pitch rate, the winds were well within limits, they did nothing of substance to address the trajectory error, and entered Class A airspace without authorization."[12] The FAA cleared SpaceShipTwo flights to resume later in September, after deciding to expand the restricted aerospace around the vehicle's flight range.[13]
