Liberty Aviation Museum, Aviation museum in Port Clinton, US

The Liberty Aviation Museum is a museum in Port Clinton, Ohio, that displays military aircraft, civilian planes, and aerospace artifacts in its exhibition halls. The collection shows planes from different periods and includes a working 1928 Ford Tri-Motor that still operates.

The Liberty Aviation Museum opened on 20 July 2012 beside the Erie–Ottawa International Airport. It owns a 1928 Ford 5-AT Tri-Motor flown on the Experimental Aircraft Association's Fly the Ford tour, and the Tri-Motor Heritage Foundation is based there, where volunteers restore an Island Airlines 1929 Ford Trimotor. In 2015 the museum won a lawsuit against Treasure Cove Marina over charges for restoring its PT-728 torpedo boat. A 12,000 sq ft hangar was completed in September 2026.

The Tin Goose Diner is a 1950s O'Mahoney diner that first operated in Jim Thorpe, Pennsylvania, as the Sunrise Diner. It became a permanent part of the museum in 2012, the year the museum opened. Its name echoes the "Tin Goose", the nickname of the Ford Trimotor.

The museum stands beside the Erie–Ottawa International Airport just outside Port Clinton, so visitors arrive by car. The Tin Goose Diner, a 1950s O'Mahoney diner that first operated as the Sunrise Diner in Jim Thorpe, Pennsylvania, became a permanent part of the museum in 2012 and serves meals on site. A 12,000 sq ft hangar, approved in July 2025 and completed by September 2026, gives the aircraft and torpedo boats more room.

The museum's collection includes a North American TB-25N Mitchell bomber, 44-86777, named "Georgie's Gal"; it was previously known as "Martha Jean". A North American Harvard IV on display was retired from the Italian Air Force in the 1970s and is painted in Royal Canadian Air Force colours, though the museum does not own it.
