Conclusions on parachute recovery

• Use of a high-altitude drogue parachute to deploy
  the pilot parachute pack
• The tandem pilot/drogue parachute method of
  deploying a main landing parachute.
• 3. Use of the pilot and drogue parachutes to
  prevent recontact of the R and R section with the
  main parachute canopy.
• 4. The concept of landing shock attenuation by
  water entry of the cabin section at the corner of
  the heat shield, thus eliminating the additional
  weight and complexity of shock absorption
  equipment.
• In conclusion, the performance of a large
  ringsail-type parachute was demonstrated by the
  use of the 84.2-foot-D main landing parachute.
