Free-fall Beaver?
Glad you all reached the right conclusion on that B-o-I then brakedwell - I remember seeing a photo of Ron B's Wessex off the ridge just after he'd released the sling with the rotor disc coned up at a frightening angle from low rpm. He hit the button just in time. Was it a Beaver or a Scout??? Or even a Sioux? Definitely an AAC bird anyway.
Were you at Khormaksar when so many of us were laid low from contaminated jungle juice from the caterers? Even staying with the canned beer and avoiding water and salads back at base couldn't save us from relying on gallons of that juice up-country. I think it got some of your trucky mates staging through too.
