VC 10 had a hatch in the fwd galley floor that dropped you down via a step into the avionics bay with a low corridor that lead you aft to a door at the rear and into the fwd cargo bay, there was another smaller hatch where you could get outside in the bottom of the floor, or of course the baggage bay door. I once after stowing the engine blanks came forward to be met with the a young Air Loadmaster in a skirt straddling the hatch while making the see off guys a coffee.. a quick cough had everyone in stiches and a slightly red faced young lady.
