Here's a short video of an initial Canopy Relative Work (CReW) jump. You can see the techniques quite clearly. Note that when fully linked, the bottom guy stops steering.
Changing position in Canopy or freefall Relative Work uses exactly the same techniques as formation work in aircraft. Before the jump, there needs to be some means of ensuring the average fall rate of the formation members is very similar. In freefall RW this is done by suit drag. As a big guy, I wear a baggy suit, whilst the women wear skintight lycra (and sometimes have lead weights). With CReW, similar wing loadings and aspect ratios are required for the canopies. After that, the only difference is how you generate the accelerations required in different directions to change position.
