Interesting perspective of a spitfire as seen from the vulcan's bomb bay. As a founder member of VTST my name is on one of those lists stuck on the inside of bomb bay doors, though I can't quite read it in the video
Note the video looks very dark to start with as bomb bay doors are closed.
In a former life we ‘erks’ had to polish the airframes after every flight using Wadpol - an industrial sized tin of Duraglit. This practice was eventually stopped as it was found to be wearing away the aluminium to the point of being structurally unsound.
