Direct answer: The MD-11 is a wide-body, three-engine (trijet) airliner developed by McDonnell Douglas as an updated, stretched derivative of the DC-10. Production ran from 1988 to 2000, with first flight in 1990 and entry into service in 1990; Boeing acquired McDonnell Douglas in 1997 and terminated further MD-11 development after completing outstanding orders, ending passenger and mixed-configuration production around 2000. About 200 aircraft were built, with roughly a quarter configured as freighters; many passenger MD-11s were later converted to freighter use. The aircraft remained in service in freight roles for years after production ended, with several operators including UPS and FedEx utilizing MD-11F variants, and certain remaining examples continuing to fly in cargo service into the 2020s and beyond. If you’d like, I can pull up the latest updates on:

• Current status and notable active MD-11 freighter operators
• Technical specifications (engines, range, capacity)
• Notable incidents or retirements in the 2020s

Would you like me to gather current data on MD-11 operators and service status?
