 The cabin has a diameter of 2.3 m (7 ft 6 in), and provides 3 m³ (10.6 ft³) of cabin space to each passenger.The seats are attached to a pendular system which allows the acceleration to be perpendicular to the back of the passengers.They pivot around the attachment points so that the passengers are aligned rearside to the spacecraft x-axis (body aligned on Gx-axis) during launch acceleration and they are rearside on the negative z-axis during weightlessness and reentry.
