The original model of the Mohne Dam used by the Building Research Station to test Barnes Wallis’ bouncing bomb theory in 1940 is being made available for public viewing for the first time at the BRE.
The final outcome of the raids in May 1943 is well-documented and made famous by The Dam Busters film (see picture below). However, the part played by the Building Research Station, as it then was, has been left out of most of the history books, owing to the secrecy surrounding it.
BRE is now opening its archives. It's fascinating stuff. You can read all about it on its website at http://www.bre.co.uk/page.jsp?id=3146
And you can visit the model dam at BRE Watford only on Saturday 25 May 2013. It is free but booking is required, via http://www.bre.co.uk/eventdetails.jsp?id=7116
