In late April 1986 (at the time of the Chenobyl disaster) we were deployed to Andoya from SM on a routine detachment. We returned the day after the disaster and were met by the groundies all in full NBC kit!!! No auto wash at SM. We were told to stay on board, and the ac was give a thorough hosing down. the crew were half expecting similar treatment as there was a 12 by 12 tent clearly marked PERSONAL DECONTAM at the side of the pan. Fortunately, the groundies got fed up of being masked up and allowed us off the ac with just a gentle spray down! Good spoof and typical of the good spirits of the time!
