Camo model at the top is not the YC-14, but Boeing C-X submission, larger tri-jet version of YC-14.

The middle model is of Boeing's entrant for the CX competition won by the McDonnell-Douglas C-17 and isn't a model of the Boeing YC-14; see:-

You're both correct, my mistake. I was concentrating on the model on the lower right of the photograph and didn't pay much attention to the model in the middle.

Always liked the looks of Boeing "three-holers", be it 727 or this C-X design. Air Force should have run a competition fly-off with the McD and Boeing designs....

Going by the lower fuselage/hull design and the dolly-type wheels, the model on the right appears to be of a flyboat?

This larger Boeing tri-engine YC-14 derivative to C-X!
Does anyone have any further details, specifications etc......???????

Would love to see and read more about this design! It's three-engine arrangement would appear to negate the concerns of the two-engine safety issue of the YC-14 design, in a one engine out scenario!

Model in the lower right looks like a twin engined Model 731 (Boeing's entry in the C-141 contest)

The fourth model in the image, still unidentified, looks very interesting too. It seems a civil airlifter.
