This is a reverse return from a Wrists Catch where the flyer then 'caught' by a second flyer hanging on the fly bar in a Crucifix position (feet under the arms).
The Crucifix position is difficult to achieve and as such this trick is only really possible as part of a sequence as follows:
1) Catch with two flyers, leaving one hanging on the fly bar (for example a Piggy Back - Trick ID: 058)
2) Crucifix Return
3) Crucifix Catch (optional)
(can then repeat Crucifix Return again and so on. This is the sequence shown in the video below.
The flyer making the return can wear safety lines for this trick (Regular Lines), while the second flyer must fly without lines.
Thanks to the team at Circus Arts Australia for providing this video.
