The Norden Mk. XV, known as the Norden M series in U.S. Army service, is a bombsight that was used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars. It was an early tachometric design that directly measured the aircraft's ground speed and direction, which older bombsights could only estimate with lengthy manual procedures. The Norden further improved on older designs by using an analog computer that continuously recalculated the bomb's impact point based on changing flight conditions, and an autopilot that reacted quickly and accurately to changes in the wind or other effects.

The Gilsum Stone Arch Bridge carries Surry Road over the Ashuelot River in Gilsum, New Hampshire. Built in 1862–63, it is one of the highest stone arch bridges in the state. It has a span of 47 feet 8 inches (14.53 m), and an average height over the river of 36 feet 6 inches (11.13 m). The roadway is 43 feet 6 inches (13.26 m) above the riverbed. It stands on the site of four previous bridges, where the river passes through a deep gorge. The previous bridge was also a stone arch bridge, which was built in 1860 and collapsed a few months later. It was designed by William Leonard Kingsbury, a local official; its builders are not known because the town's records were destroyed in a fire. The present bridge's vault is carefully constructed from dry-laid granite voussoirs that were shaped for a very precise fit, with larger stones at the lower ends of the arch, and a smaller ones at the crown. Some of the stones were left with rough surfaces, while others were hammered smooth.
