Aviation Museum of New Hampshire is a volunteer-run nonprofit at Manchester-Boston Regional Airport that preserves New Hampshire aviation heritage and inspires future aerospace pioneers. Its 1937 passenger-terminal and control-tower building, together with the Slusser Aviation Learning Center, present regional aviation history, aircraft, artifacts, archives and interactive education. Public hours are Wednesday–Saturday 10:00–16:00 and Sunday 13:00–16:00; other group or private visits are by appointment. The museum is outside the airport’s secure perimeter; visitors arriving by aircraft must park at Signature Aviation and arrange any available shuttle or on-call transport rather than access the museum from active ramp areas. The operator publishes current admission categories, holiday changes and volunteer-staffed arrangements separately, so confirm before travel. Visitor address: 27 Navigator Road, Londonderry, New Hampshire 03053, United States.
