4 simple steps to creating a 4-way tandem suspension:
Step 1: Hook up the top person using 6 Gilson hooks just above his knees, and then another 4 in his torso to hold the rigging plate below him.
Step 2: Repeat step one
Step 3: Add the last 2 people using a 2 point suicide for both of them, with knee hooks to join them together.
Step 4: Step back and watch the four people enjoy an amazing suspension.
Remember to only attempt something like this in the presence of skilled practitioners and the difficulty level for something like this is astronomical. One thing to note is that the top person has a secondary harnesses attached as a backup in case of hook or skin failure.
Congratulations to Moscow’s Sinner Team for pulling this off safely.
