Concerns with this are pretty straight forward. Spoil the lift of the leading edge and on the elevator. The last thing you want is the plane below flying up into the helicopter. Also, having done this several times now, the need for a tag line is key for your ground folks at the other end due to the fact that once the plane hits ground effect it starts to spin. Ground handlers can grab it pretty quickly and control the spin if need be. Honestly, we don't want anyone around the plane as we are setting it down however the owner always wants to help with that part in order to save whatever may be left. In this case, the plane will be totaled anyway. Here are some pics...
The plane was pushed back about 500' from the actual ground loop location to where you see it here. Cub was a friend of the pilot.




The plane flew perfectly back to town. About a 15 minute flight from the location here
