Two flyers swing side by side (each has half of the bar). Many tricks are possible - splits, planche etc. You can also turn around together and get back onto the board.

This can also be a great way to teach someone a swing - let them swing side by side with a more accomplished flyer and they learn the leg movements by copying!

These notes are provided ONLY as an explanation of the trick.
If you want to perform it yourself - get an expert to teach you.
