Went to the TWA museum. It’s located in the TWA headquarters building at KMKC. It’s all still there. The building is owned by a fractional ownership company, but it’s exactly the same building. Jack Frye’s office on the second floor. The original hangar for maintenance in the DC-3s. So much history.
It’s run entirely by volunteers and donations. The workers were either employees or frequent TWA fliers. They also have a section dedicated to Ozark Airlines as well
