Each fairing half is equipped with a steerable parafoil and thrusters which allow the fairings to land in the ocean or on a ship with a net. This list contains all fairing recovery attempts and will be updated over time.

It is a unique way of fuel transfer between the side boosters and the center core of a rocket. It increases payload capacity but was never actually developed in practice.
