MRO became a prominent industry in Tulsa, Oklahoma when American Airlines relocated its Tech Ops headquarters from New York’s LaGuardia Airport to Tulsa in 1946.[1] Since then, commercial MRO facilities at Tulsa International Airport (TUL) have become the largest in the world, including 3.3 million square feet of hangar and shop space sitting on 330 acres.[2] On average, more than 900 aircraft visit the facility in Tulsa each year, which accounts for 1 out of every 10 commercial US aircraft. Tulsa has earned the nickname the ‘Airline Maintenance Mecca’ because of its over 50,000 person workforce.
A Higher Calling dives into the world of cargo airplane repair, following the lives of veteran MRO mechanics, facility managers, and first-year engineers who do the high-stakes, behind-the-scenes work often taken for granted in shipping, delivery, and commercial air travel.
Filming for the series began in December 2020 and wrapped in May 2021. The documentary series is expected to premiere via Amazon Prime Video in the near future.
