Stefan Janus recalls:
        I commanded the 315th only for few months before I was shot down and became a P.O.W. Since everything was already written about dog fights, shooting and so on, and very little about cooperation between pilots and ops-rooms, I ‘d like to recall one event which illustrates how difficult this sometimes was, especially when dealing with young pilots.

    One November evening, before a session of night training flights, I had a shorts briefing with a bunch of young pilots. I issued an order for pilots to have aircraft position lights on during take-off and landing. It was to be a short flight: take-off few rounds in airfield vicinity and landing. When third Spitfire took off I received telephone call from ops informing me that soon an enemy aircraft will pass near our airfield and my pilot is flying with his position lights on. Wrongdoer received an order to turn them on. He confirmed it but somehow couldn’t remember how to switch these lights off. During a few anxious moments that followed, the controller tried to calm down the pilot. On a direct pilot’s question:
How the hell you turn these bloody lights off?!, the controller not knowing Spitfire cockpit procedures and having nobody around to answer that replied: Try the opposite way you turned them on.
The lights went off in an instant and we all breathed with relive. Pilot had enough of flying for that night and soon after landing received a lot ribbing in NCOs mess. In officers mess we had our share of laughs as well.
