In 1959 I flew to Singapore in a Britannia of Hunting Clan Airways when my father was posted to Changi. Sitting over the wing during engine start at IST (stopover for fuel) a large sheet of flame came out of the exhaust on number 2 engine. Looked like a hot start to me. Who were Hunting Clan? You never see any reference to them. We returned to the UK via ship,(as interesting as watching grass grow). I am now based out of SIN myself as a pilot, funny world. Incidently the other fuel stop was Colombo where we stayed overnight in a Hotel called Mount something, very long layover. Now I regularly fly the route in 13 hours. I think I was born to late!
