This is a simple 'Straight Jump' style catch from a position where the flyer is hanging in a Crucifix (feet under the arms) from a second flyer on the flyer bar, to the catcher's 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
(can then repeat Crucifix Return again and so on. This is the sequence shown in the video below.
The flyer can wear safety lines (Regular Lines) for this trick, but the second flyer must fly without lines.
