In 1979 we were doing the Teeside-Ekofisk run with S-58T's....still using Decca, Two Channel SAS (seems the Yaw Channel never worked)....single pilot. At least we had a second engine and Monochrome Radar. Fuel calculations were a constant effort as we were always to have onshore diversion fuel.
We also had T-Birds in the Shetlands and out on the Ninian doing the Shuttle. The Shuttle was done with Two Pilots for some reason but not the Runs to the Rigs/Platforms from ashore.
While based at Teeside, I took up Parachute Jumping with the Parachute Club at Sunderland Airport....and flew the Jump airplanes there as well. Many a fine day and evening there with very warm hospitality.....in time I finally got to the point I could understand and speak a bit of Geordy!
