The cabin on this specific airframe is recorded as a converted tanker / convertible passenger-cargo layout, with refuelling modifications reported, indicating air-to-air refuelling capability or tanker support role in addition to passenger-cargo flexibility. Detailed avionics fit and configuration are Not published; maintenance considerations therefore may vary based on the extent of conversion work and refuelling system installations. Based in San Antonio, Texas under Omega Air Inc ownership, the typical mission profile for this airframe would logically include medium- to long-range ferry or tanker sorties consistent with the 707-338C platform’s range and cruise performance. Unique operational considerations for this aircraft include upkeep of vintage JT3D turbofan engines and any supplemental systems associated with its tanker modifications.

The Boeing 707-338C represents a long-range variant within the 707 family, and this airframe’s combination of a 3,735 nm range and 525 kts cruise speed places it in a niche for transcontinental or extended regional operations for its era. Competition in the vintage four-engine jet market typically comes from other early-commercial jets and converted freighter/tanker platforms; buyer and charter demand for such types is specialized and often focused on niche roles rather than mainstream passenger service. Maintenance and resale considerations for this aircraft are influenced by its 1968 build year, serial 19623, the presence of legacy JT3D engines, and the extent of conversion to tanker/passenger-cargo use, all of which affect parts availability and regulatory compliance costs.
