I remember there was a documentary series, six episodes I think, entitled Test Pilot on BBC 2 ? There was also a book released at the same time of the same name. Each week it featured two or three of the ETPS a/c types being put through their paces by the trainee Test Pilots. Hope this jogs your memory as I reckon you will be lucky to find any internet footage??
The book by Brian Johnson published by BBC books ISBN 0 563 20502 4 in 1986. Hope this helps.
