S1 has invented a spacecraft named the Quad Power Rocket QPR. The QPR is a combination of one quadcopter drone machine and a powerful rocket. The rocket accelerates at peak velocity and then the quad rotors take over to land the craft on the Earth. Some interesting features are as follows:
* The craft can land upright
* The craft can land at the launch site
* No parachute needed
* Directional landings
* Compensation for wind drift
* Easier find and recover
* Landings have soft deceleration
* No landing Gs
