Mid 80's, Portadown NI, Eagle VCPs with the UDR on a weekend. Call from patrol to be picked up from a playing field where they were being harrassed by locals. We arrived to see a group of kids aged 8 - 15 approx, mostly on bicycles who had been pursuing said patrol hurling stones and abuse. We landed on, embarked the troops and performed a cushion creep style transition over the top of the yobbos with a max power pull at the moment critique. We circled round in the climb to witness said yobbos and bikes spread out in a flattened daisy pattern - they learned about helicopter downwash that day
