A Heavylift Belslow delivered a 57ft long periscope to ASI for onward delivery to FI. Now there was a reason for using the Belslow rather than a Herc - load length.
Flying down to FI with the tail gate open wasn't on. One of the movers had a great idea. The Top of the freight bay was long enough so the laid it on a platform so the ramp could be closed.
