To get in you:
- park your car, and walk to the entrance
- present your passport
- stand on an X and have your photo taken
- take the ticket with you photo back to your car
- enter the site, go to the specific location and no other, and park
- enter the museum and pay
There were quite a few exhibits with a long explanation, but the explanation was only at the "the floggle is connected to the flugle" - little if any explanation of what floggles/flugles were nor how they work. (I think the limit of technical explanation were the words "packet switched network".) Sufficient, however, for a trained grunt to assemble and operate it.
There were quite a few "human story" exhibits. Yes, I know these are generally fashionable, but these tended to be "X did Y very bravely and got a medal". The obvious subtext is "and so should you maggots".
There was only a nod to sigint and its contributions. A sign indicated previous sigint heroes on active service weren't paid out of the army's budget. Presumably they don't count for much.
Most interesting exhibits were a scope and enigma machine, and a computer drum memory that was used for crypto until 1975. No, of course there wasn't any indication of how it did that.
Glad I went, but I won't return.
