The first two legs had been smooth as silk and the weather had cooperated, giving us cloudy but otherwise fair skies. However, on this segment we were encountering darkness, lowering cloud, the odd bit of fog and occasional light rain that would pepper our windshield. Still, with nearly 50 years and 2,000 hours of flying time between us, we felt comfortable and very confident in our ability to complete a safe flight. Cocooned in our David Clarks we talked casually over the intercom about a number of subjects, including the capabilities and features of our new acquisition. We were also getting very comfortable in the operation of our new GPS. Below us widely scattered lights from the farmhouses flickered as small areas of fog and haze passed. Other than the steady drone of the engine, it was unusually quiet with very little radio traffic. As the flying pilot I had just informed George that we were within 20 miles of Peterborough, our destination airfield.
