VSS Unity — also known as SpaceShipTwo — will, over the course of a 90-minute flight, offer a few minutes of weightlessness to six passengers at a time, as well as views of the curvature of the Earth — the vessel should reach an altitude of around 100 kilometers.

According to the document, the company plans to start with 16 flights a year in 2020, then to increase this to 270 flights a year by 2023, when it will have its entire fleet of five vessels — which works out to around one flight every 32 hours.

Within four years, it will eventually have the capacity to transport 1,565 people on a year-round basis.
