This has nothing to do with money and everything to do with management and organization. They could have over $100M and do a terrific job, using volunteers like the Computer History Museum does in Mountain View. It’s clear there’s been waffling and wavering on the management of Bletchley for the last 20 years. The Churchill Museum on the site was excellent - many said in its prime with better exhibits than Chartwell - even though the building was shabby. There are ways to run the site that are better than the status quo and I challenge the British government, Friends of Bletchley Park, National Museum of Computing and Bletchley Park board to get their act together.
Disclosure; my husband is on the board of the Computer History Museum in Mountain View, CA, where I was also a volunteer. I have visited Bletchley Park and been shown around the site by someone who worked there in the war - she gave me a wonderful visit.
The opinions in this post are my own.
