My intro to helis was a holding pilot at B flight RAF Leconfield, then equipped with Whirlwinds. The crews hadn't been able to do much recent training due to recent bad weather so they used me as a professional survivor for a few weeks.
One drizzly evening I was winched down to the Bridlington lifeboat. A certain large MALM used a double strop technique to get us both down to the deck, with my legs dangling lower than his. As I touched the deck, I suffered an almighty static jolt, which caused both my knees to convulse upwards, right into said winchman's wedding tackle. He didn't speak to me much for a while.... or anyone else for that matter.
