|Although hardly a frontline combat aircraft, the USAF's C-140s did see use in forward areas, and some were refinished in camouflage.|
The Jetstar first flew in September 1957; the prototype was powered by a pair of Bristol Orpheus engines, but production aircraft had four P&W JT12s. The C-140As were used for navaid checking, while the five C-140Bs and six VC-140Bs were used as light transports.
