Conversion of one C-119B to meet USAF requirement for an experimental detachable-fuselage transport; C-119B wings and tail surfaces combined with new upper fuselage component with a flat surface; lower component with flat upper surface, and incorporating cargo compartment, could be mated with the Packplane; flight deck in upper component; the type could be flown with or without pack and it was intended that various packs for different military operations would be provided; first flown on 11 August 1950; no production contract followed military evaluation.

Ran some wind tunnel runs with a model of this acft. A good description of the fuselage without the "packet" would be a "poorly designed airfoil". The stability issues were due to significant turbulence aft of that airfoil, which disrupted the effectiveness of the horizontal stabilizer, and to a lesser extent the vertical stabilizers because of interaction with the horizontal planes. On the model we "solved" the problem by moving the horizontal stabilizer to the top of the vertical fins, rather like an OV-10 Bronco. Some rather minor reshaping of the fuselage then resulted in a model that was near impossible to stall. The design had potential that was never explored.

Saw jet mode in movie Journey to the Far Side of the Sun & in Thunderbirds TV show for Thunderbird 2
Viable Today for sure.
we are launching bee-plane project and are looking for XC-120 information. Please contact us !

Was the only prototype scrapped or does it exist anywhere...?

@JIm Winnie did you feel like the landing gear was unstable
Glad they only made one.

I flew in this aircraft as a flight engineer in 1950 at Eglin Air Force Base testing the aircraft. I found it to be very unstable without the fuselage on it. Glad they only made one.
Do you have any comments about this aircraft ?
