Those interior pics of the -46 and -47 don't give a real feel for the differences in size. IIRC, the -47 will seat 44 troops, and in addition to the cabin being taller, it's substantially wider. In the late 1970s I spent some time with a Navy squadron flying UH-46Ds, and did some flying on CH-47Cs from the US Army Aviation Logistics school. The other difference I remember is that the Navy guys didn't spend as much time as the Army cleaning up the hydraulic fluid leaks endemic to both airframes. The first time I stepped onboard a UH-46 I entered through the forward cabin door. I was wearing leather-soled Corcoran jump boots, and I slid the complete length of the cabin to the ramp before I could grab hold of something and stop. After that, I always wore vibram-soled jungle boots when flying with the Navy. So if you're doing a CH/UH-46, make sure to use a gloss finish on the cabin floor :^) |

I've crewed both types
4.5 years on CH-46D/F/ and Es with HMM-162, HMH-461, and HMM-164
17.5 years on CH-47As/Cs and CH/MH-47Ds with 132nd Avn Co 213th Avn Co. B Co, 2/160th SOAR. H Co 2/159th Avn. A Co 2/501st Avn and B Co 2/159th Avn
I've often heard the claim that '46s and '47s were notorious for hydraulic leaks and that the interiors were completely covered in hydraulic fluid (this, invariably from those who never crewed them), yes there were some leak points on both types, but only a complete slob would let their aircraft get to the point where it was a slip hazard such as you describe.
CH-47Ds have seating for 33 troops, CH-46s had seating for 25 troops. Newer versions of the CH-47 have additional seating in the aisle... However the number of bodies that can be packed into either type is not restricted by the number of seats. When I was with the 160th we routinely hauled between 50 and 75 troops...usually SRO and no seats intsalled.
The interior of the cabin on CH-47s is about four-five feet longer than on CH-46s. What accounts for most of the increase in interior size is the fact that the interior cabin dimensions on CH-46s are something like 6' wide by 6' high, and on CH-47s the dimensions are 7.5' wide by 6.5' high.
Also, you must have had leather soles put on your Corcoran jump boots, because for as long as I can remember, all the pairs that I bought during my 17.5 years in the Army (1980-1997) had rubber soles, and the ones that my father wore while he was in the Army (1947-1972) never had leather soles on them.
