After I finished the NBS course at Lindholme I did a few trips as nav in the Hastings while waiting for my Victor OCU. One was a trip to Stornoway whose sole purpose, as I recall, was to bring back various items of seafood.
All went well until on the return trip someone called out that some of our "passengers" had got loose. Much scurrying around the rear of the fuselage ensued as we collected up live lobsters which had escaped from their crate and were making a bid for freedom.
