Love the Nissan huts.

Have you seen the underground facility at Wellesbourne airfield?

I served my time on an old airfield there was plenty of stuff like this to explore.

I'm a little too old to go grubbing around and climbing over these days but used to do a fair bit in my youth. As a 15-year-old, I scaled the gates to the Nothe Fort at Weymouth. This was long before it was opened up to what it is today. It was a complete ruin, but I had a great time looking into all the odd crevices and rooms.

I also worked at a secure mental health unit that has featured regularly on 28dayslater.

The basement at Canley's Triumph factory was also something to see.

The Wellesbourne facility is (was) maintained by the same people that run the museum. It was stumbled on by accident and was flooded. They pumped it out and for a while would give tours. It's been years since I went round the place.

As an aside, last time I was at Wellesbourne I had an interesting discussion with a member of staff about an aircraft control column. He reckoned it was off the (then) current Shackleton (Mk2) AEWs. I disagreed as I'd worked on Mk2 Shacks. It took me a long time to verify that it had actually come from the Mk3 Shacks which had been scrapped years earlier.
