Swan Necks dirty smelly things
5ADay, fortunately for me I arrived at Wattisham straight out of Shawbury whilst the runway wasn't. A runway that is, just a long but narrow hole in the ground full of contractors and diggers, mechanical as well as human, and after many weeks this hole in the ground was returned to the station as a pristine "new" runway. This was when I was introduced to the latest in high tech, emergency runway lighting, THE GLIM LIGHT! a battery powered lamp with a 6v car type battery and which was maintained IIRC by the ground engineering section.
