We must have been at the same signings.

I have assumed that the firing butts were the brick walls with the supports. I have seen pictures of a similar structure near to one of the hangars (probably the tit lake one you mentioned).

Not sure what people meant by an underground base? There are some underground control rooms near to where the guard house was - all filled in with bits of concrete when we were kids.

i think the structure in question is a blast wall,for the building behind it,t.v program, two men in a trench did a show there,as you probably know,they found 303 shells from firing butt area ,but speaking to john,he said they had to go through 2 metres of 70s landfill to get to them,and the local kids terrorised the security for the set overnight.
