Gosh, weren't SH aircrew slender in those days?
Must have been before the latter part of the 1970s? Dog's N** is sporting open intakes (pre PIP intakes) and metal blades, those mods came in during the late 70s/early 80s. Also both crew have pre-nomex flying suits, at least the Pilot has.
I'm just trying to recognise those two lucky chaps with the smeared faces.
