It sounds to me like you could be talking about "Climb to the Lost World" which was a 1973 expedition to climb Roraima, by Hamish McInnes, Jo Brown, Don Whillans and Mo Anthoine. McInnes wrote a book of the same name, and A BBc Scotland camera crew went along to produce a film. I don't think it's ever been released on dvd.
I was lucky enough to hear Don Whillans describe this expedition as part of a slide presentation in 1983. He was a brilliant storyteller as well as a superb climber. Sadly he died just a couple of years later.
Thanks for posting, it looks very interesting. I've thought a few times about heading to the Isle of Man for walking or cycling but not made it yet.
I've not had chance to fully read your trip report yet but I certainly will. A lot of the photos remind me of the coast around Anglesey and the Lleyn peninsula, which are regular stomping grounds. It looks like I really must make that ferry trip...
Trev, what I almost said this morning was that I just put "windy" into the OM search box, then restricted it to Forum results, and both threads were there to read. And it's worked again now. But it does seem to fail sometimes, possibly if you use the back button on the browser... not really sure, but then OM's web coding never was all that robust, was it? Anyway, it looks to me like they aren't totally lost if you want to revisit them.
