A Higher Calling: Inside America’s Airline Maintenance Mecca is a proposed American documentary series in production as of 2020[citation needed].

[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.

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.

The documentary series is expected to premiere via Amazon Prime Video in the near future.
