FT: There are many documented cases of pilots reporting sightings of UFOs, or at least things they couldn't explain. You were once a very active pilot... in all your years of flying, did you ever see anything that, whether you're sceptical or not about such things, remains hard to explain?

GN: Nothing at all, I'm sad to say. I wish I had. The most alarming thing that happened to me in the air was when I had bits fall off an aeroplane I was flying upside down, which certainly came as a surprise. I've also had them catch fire, break down, and scare the # out of me on more than one occasion, but nothing of an alien or supernatural nature. I did see something that I have never been able to explain when I was driving home from the studio one night – a large light in the shape of an upside down pyramid focused at a point on the road near me. I also saw a ghost once, so I am completely open to the existence of such things, both alien and supernatural.
