Longwell Airport

The specific reason is not officially documented. However, its closure is consistent with the trend of small, privately-owned general aviation airports of that era shutting down due to economic pressures, rising land values, increasing regulatory burdens, or the owner's retirement. There is no evidence it was closed due to a specific accident or for military conversion.

The airport is permanently closed, and no trace of the original runways or facilities remains. For many decades after its closure, the land was reverted to agricultural use. As of the early 2020s, the site and surrounding area have been developed into a large-scale commercial solar energy facility, known as the High River Solar Project.

Longwell Airport was a small, private general aviation airfield that served the local community of Amsterdam, New York, from the early 1950s to the mid-1960s. It was named for its owner and manager, George Longwell. The airport featured two unpaved, sod runways: a 2,200-foot north/south runway and a 1,600-foot east/west runway. Operations were typical for a small field of its time, handling private aircraft for recreational flying and likely offering services like flight instruction and aircraft storage. It represented the grassroots level of post-WWII aviation growth in rural America.

Zero. The airport has been defunct for over 50 years, and all aviation infrastructure was removed long ago. The land has been completely repurposed for a long-term industrial use (a solar farm), making any prospect of reopening as an airport infeasible.
