Ransome Airlines, Pan Am Express (PAE), and Trans World Express (TWE) are predecessor and successor domestic airline companies. Ransome Airlines was a regional commuter service that operated between 1967 and 1986. Pan American World Airways acquired Ransome Airlines in April 1986 and renamed the company Pan Am Express. It operated domestic routes for the first time in the parent company's history. When Pan American World Airways went bankrupt in 1991, their wholly owned subsidiary was purchased by Trans World Airlines and became Trans World Express. It continued to fly domestic routes until 1995. This collection of Ransome Airlines, Pan Am Express, and Trans World Express records documents the three airlines from the initial establishment, through each transition, to the final dissolution. While not a complete company archive, the records provide a representative and detailed view of high-level operations at Ransome Airlines, PAE, and TWE through the activities of various executives. The collection contains the papers of five company presidents, three directors of finance, two directors of public relations, one director of personnel, one director of planning and administration, and one member of the accounting department. It will be of high research value to aviation historians interested in the effects of deregulation, aircraft acquisitions, financial planning, company mergers and transitions, and bankruptcy. The collection will also interest labor historians involved in collective bargaining research.
