Whilst serving in the RAF in 1975, I was a security guard on a VIP Comet a/c travelling round the Middle and Far East, Australia and New Zealand. On one leg of the trip we landed at Alice Springs for a 2 hour refueling stop. I drew the short straw and had to guard the a/c. After thing had quietened down an Australian customs officer walked over to the aircraft and greeted me in a broad Scots accent. Being a fellow Scotsman , I asked him where he was from, to which he replied "Near Edinburgh".
