Burundi

Our plane from Nairobi to Kigali, the capital of Rwanda, couldn't land due to fog, so we went on to Bujumbura where most of the passengers disembarked. We had no idea where we were so we asked our fellow companions. Burundi! We were allowed outside the plane to stretch our legs, but within 50 metres of the plane was a paddock with about 50 well-armed soldiers, and a solo soldier with a very large gun the bottom of the exit stairs, so didn't feel inclined to put my foot on the tarmac so I could honestly say  we'd been to Burundi so I stayed on the steps. We were on our way again after a couple of hours, it was a fun  diversion.
