They do allow people through the Sunderland Adlabs, but just my luck to go on a day it was closed,

some other areas were closed also,the upstairs area you can see in the JU87 shot which seems to be a control room, and an upstairs engine gallery, seems like there was a pattern here to do with stairs, a safety issue maybe? but still plenty to see.

The bomber Hall is kept quite dark for visual effect, but that didn't help the photography.
