Yes, Bovington Tank Museum is quite an attraction, and it's also near Monkey World so you can make a good day out of it. I'm not sure why Bovington is being used for these night flying exercises, though as it's not a regular base.
When I was at school we where at blandford dad in the army
Royal Signals, Saundra?

Blandford Camp is still going and I think there's a regimental museum there although we've not actually visited it. We did go up the top of Bulbarrow Hill near there last year and there were a number of squaddies in bivouacs with radio equipment all trying to contact each other!
