I'd like to get hold of a copy of that as well!
The beeb are good at denying all knowledge of docs theyve made I appeared in one on the simulator on VC10 and afterwards cos I was on the BALPA council at the time they had me chatting about pilots conditions etc They obviously wipe the tapes to re-use them and they are no longer available.
Mine was approx 1972, If anyone has a VHS tape of that Id appreciate knowing about it.
