Major Tom was never in contact with Dakar obviously, as I have never heard them ask for Crew Uniform details, and the lyric also fails to mention other reporting points on the route to Freetown.
However, it is still possible that Major Tom was indeed on his way to Freetown eventually, but may have been burned to a crisp encroute upon re-entry.
If he survived however, the Nasa base at Banjul would have been able to arrange for a clean shirt of the appropriate manufacture.
Were this to happen now, it would be with great pride that British World would transport his shirt without losing ours.
I must be going.. the Cheese tray has arrived.
