G-ALHI:
The big problem with the C-130 is that there are an awful lot of things that won't fit in it. For example, a C-130 centre section will not fit in a C-130 when it comes time to replace it when the original item is falling to bits.
The whole thing about the Belfast was the 12 ft square and 90 ft long freight bay. Try getting a Sea King helicopter in a C-130 or, even better, 2 Pumas. In fact, the C-130 cannot even carry something simple like a CF-6 powerplant without a major teardown.
Frankly, you are comparing apples and pears.
I notice that you use an Argonaut callsign. I suppose you would describe that as a Canadian-built American aeroplane ruined by British engines?
