XV 206 - Midair Collision
Both the Herc and Sea King were searching for a North Korean fishing boat that had been fired at for fishing "illegally" in Argentinean waters and was moaning all over the Marine VHF about it.
Think the RN Sea King was off RFA Argus but not sure, as it was a long time ago.
The weather was indeed a "factor" in the Mid-air IIRC the Herc was still IMC when it hit and originally thought they had hit a mast.
Remember watching the Herc recover at MPA and the circle it did before actually landing on the then very new FAPADS. Then when to work plotting the search on the old totes, location was N of Byron.
Me I was a lowly SAC at JHQ Stanley.
