You were lucky to miss that trip. I did it once, a couple of hours in a Dormobile from Akrotiri then an eternity in the Hastings, Nicosia-El Adem- Khartoum- Aden.
As regular visitors to Aden there was always a long shopping list and pre SBA no customs. After independence a couple of UK Customs appeared at Akrotiri. It was funny how ATC were always quite slow to tell them of our arrival and there would be nothing to see when they made it to our dispersal.
We always had numerous large cans of undeveloped film with TS sortie numbers which had to go urgently to the photo section. Not all of them would contain film.
We would go on from Aden to Eastleigh where the locals looked after us very well. The SATCO asked us if we could get him a camera next time we were there.
Better than that you can get it yourself. By a pure coincidence we might find that film stocks here are running low so a quick day trip to Aden is necessary. Spare jump seat if you want it tomorrow. One very happy customer.
