Not a joke but a bit of fun;
When we were all getting out of Aden in 1967, some idiot (or maybe there was more than one) sent out a standard repatriation form for all of us to fill in.
One of the questions was:
"Where is your nearest railway station?"
"Djibouti" said my navigator.
As in all matters "navigation" this was totally accurate but totally impractical,
That would indeed have been an interesting journey.
