Bratman - thanks for your efforts - well worth it as they are super pictures (I love the old Vauxhall, by the way, Singapore was full of old cars that had all but disappeared from British roads at that time).
I was fire officer at Seletar at the time, and one night we had an unexpected visit from a Javelin after the airfield had closed. An airman walking along the road which crossed the runway from East to West camp when a Javelin appeared out of the darkness, flew just over his head, and plonked itself down on the runway just past him. Cant remember what the problem was but it must have been a pretty dire emergency for him to choose not to attempt to make it to Tengah, only a few miles over to the East. Do you remember the incident?
