Almost 15 years ago, I had a look around the 'FLA' mock-up at Farnborough. In the freight bay was a large orange structure which looked like a (kevball) goalpost. "What's that?", I asked my host. He replied that it was a C130J fuselage cross-section representation.
It looked tiny in the cavernous interior of the FLA. And that was the FLA's biggest snag - it was thought of as a 'Funny Looking Albert' rather than as a revolutionary airlifter.
