Menwith Hill / NSA

At DefCon III, someone had a video on these ladies ("granny hackers" was the comment from the audience) who explore[d] the Menwith Hill NSA base in the UK. The video was shown twice from what I remember, once in the main speaker room and once in the video room. If anyone knows anything about this video then please email me [tobin@mail.edm.net], especially if you know WHO had it, where I could get a copy, etc. Also, I'd like to hear about any other similar type things. (crypto, NSA, etc) Thanks, Light Ray
