Tasked for a bit of troop training, a mate and I took a Lynx to Sennybridge for a couple of days. We were tasked from the camp in Sennybridge itself to start lifts on the area after first-light, but day one dawned a little claggy. We got airborne and called-up our customer on the radio, and asked him about the vis on the area. "Four feet" came the reply, with a hint of Nepalese. "Are you sure?" we enquired, as we could see a good deal more than that "I can only see four feet" he assured us. By this time we'd found the troops, so we landed, shut down, and went to have a chat with the Toms, whose Radio Operator was sat inside a 9x9, four feet away from the tent wall.
