That's an interesting story.
The Flite-Control Wad was developed by a female engineer at Federal Cartridge and was originally released for turkey hunting. The part that holds the shot column is a tube that does not peel back, so it keeps the shot payload inside an enclosed cylinder for a longer distance when leaving the muzzle. Then, "vanes" at the rear spring out to act as a parachute that drags the wad off the payload from the rear instead of the front just peeling open. That way the shot continues downrange almost undisturbed.
