ValMORNA as Fire Officer at Kai Tak I had occasion to drive up the mountain to do the annual fire inspection at the unit. I was denied entrance by the aforesaid CO as I didn't have the requisite security clearance. As a fairly junior flying officer I couldn't really argue with him but I did point out that I couldn't sign off the fire inspection. He said if the place burned down he'd take the blame!
As you say -an "interesting" road journey.
Incidentally our weekly poker school in the mess was joined for a while by a CIA man who worked "up the hill". We thought this lent an air of glamour to our game!
