When did the RN sanction travel in working rig?
At the risk of incurring Wholigan's wrath, I feel that it's just worth mentioning that it's highly possible that the "killick stoker" mentioned at Post 69 in the thread Airline Travel in Uniform, could have been a Cat A compassionate case, landed straight off a submarine and thus with no access either to plain clothes or smarter uniform in the rush to get him on a flight south.
To give the poor fellow (and the RN) the benefit of any doubt, maybe an edited version of this post could be added to the end of the closed thread?
