PVR, I recall that the Puma was slightly damaged during landing, the Gazelles arrived to assist and were more badly damaged. The Puma flew out. Another case from around the same era was the tale of two Gazelles suffering a "shunt" when one landed in a Norway carpark. Shortly after landing it slid down the icy slope into a snowbank. The second arrived to assist, landed on...and slid into the first. OOPS!
