Second flyer hangs from the first flyer's neck and makes a Pelican catch
1 Back Somersault
Both flyers leave the platform together. The first is hanging under the bar and the second holds the first flyer's neck/shoulders and hangs underneath. The second flyer holds a small set, then sweeps their legs back and forwards again, opening them until they are in front of the flyer's face. At this point the flyer let's go and opens for the catch. See the 'Pelican' for more information. The first flyer does a Pullover at the frontend and returns to the platform with an Uprise Back Remount.
