About VC10 and also VC15 galley floor trapdoors. The VC 10/15 required an inspection to check the hyd quantities and a few other things under the floor each transit. But, in the best tradition of British engineering, we had to take up the trapdoors in the galley and hence prevent the galley exchange form going ahead while we, engineers, were down there checking the stuff required. We used to be blamed for any delay. Not my airline, blame me if you want.
Can you imagine it - an aircraft designed when the VC10/15 was designed having fuses for the systems? There is lots of other lunatic design stuff but let's leave it for another thread.
