By the time we returned to Litch-field, about 20 minutes after we left in clear conditions, I couldn’t see the ground through the cloud deck. Fortunately, we had a full moon and clear skies above, which provided good VFR conditions on top. As a VFR-only pilot, I needed to find a place to land. It is my practice to always leave the ground with full fuel, so I pulled the throttle back to 2,100 rpm and felt some comfort in the fact that I had at least 3½ hours to find an airport that was still VFR. We headed south hoping to land back at Hutchinson, but the cloud deck had also engulfed Hutchinson and well beyond. We couldn’t see any ground lights in any direction.
