formally activated later in 1941. The depot was the site of a Douglas Aircraft factory producing approximately half of the C-47 Skytrains used in World War II. The site also produced a number of A-20 Havocs. Production ceased in 1945. The first successful tornado forecast in history was issued on 25 March 1948 from Tinker, about three hours before a tornado hit the southeast corner of the base. A granite marker in the Heritage Airpark on the base commemorates the event. On September 29, 1957 Buddy Holly and The Crickets recorded "An Empty Cup", "Rock Me My Baby", "You've Got Love", and "Maybe Baby" in the Tinker Air Force Base Officer's Club. The base hosted the Space Shuttle Columbia and its carrier 747 on April 27, 1981, after its first mission (STS-1) during its journey back to Cape Canaveral. Oklahoma governor George Nigh, Oklahoma City mayor Patience Latting and Apollo 10 Commander Tom Stafford were there to greet the crew. The visiting personnel included Deke Slayton, who traveled beside the craft in a T-38 chase plane. An estimated 100,000 people were allowed to enter the base and take pictures. On 14 November 1984, a massive fire that burned for two days destroyed or damaged over in the Air Logistics Center, Building 3001. The resulting repairs cost $63.5 million. During much of the 1990s, Tinker was home to the Automated Weather Network switching facility, which consolidated all U.S. military weather data worldwide. Originally located at Carswell Air Force Base, this unit was later moved to an Air Force Weather Agency facility at Offutt Air Force Base. In May 1992, Tinker became home to the Navy's "Take Charge and Move Out" (TACAMO) wing, which provides maintenance, security, operations, administration, training and logistic support for the Navy's E-6B Mercury aircraft fleet. TACAMO was the first Navy Air Wing fully integrated on an Air Force base, carrying out a Navy mission in joint operations. On 3 May 1999, a deadly tornado caused extensive damage to the northwest corner of the base and surrounding communities. For many days afterwards, Tinker personnel helped by providing shelters, search and rescue, and clean-up efforts. The Oklahoma Maintenance, Repair & Overhaul Technology Center (MROTC), a public-private partnership, was started in 2003. MROTC is managed by Battelle Oklahoma and owned by Oklahoma Industries Authority (OIA), a public trust housed in the offices of the Oklahoma City Chamber of Commerce. The
