The 18 sqd one on the pan caused quite a bit of damage as the blades struck the tunnel covers/roof, but no one knew the droop stop had failed and fallen off post a heavy landing in a field.
During the Turkey operations post gulf 91 an american chinook landing near our tent accommodation with a rear droop stop stuck out and we utilised the fire hose approach which worked a treat, the 7 sqd guys also suggested the giraffe approach but that was not feasable where the aircraft was, don't think there was any giraffes either come to think of it.
