Also off topic:
I flew on Victors in the RAF in the sixties and seventies. We had a co-pilot known as 'jaapie' - ie from South Africa- and he had a hand gun for which he had a licence..When we did tanking sorties in the Middle East he always took his gun with him. He held it in a shoulder holster under his flying suit.He left it in the cockpit when we night stopped. Not sure he ever declared it to the Customs at Marham but he did have a Firearms Certificate for the gun.
