Yes I remember Tony Downie at Blackpool and met him again at Exeter.
I flew in YF about a week before it was withdrawn from service, it was one of the ex Malaysian 400 series that was brought back by BAF in the late seventies, very heavy aircraft, we carried out a weight reduction programme at JEA when it was converted to a freighter, we found a 2 inch loom running along the leading edge, couldn't work out what it was, it transpired that it ran to loudspeakers that were once fitted on the wingtips. The RMAF used to fly over the forests broadcasting propaganda.
Useless information snippet for today.
