Visit May 2008 - The approach entrance into Brockzetel.   The guardroom on the right, which wasn't there in 1956, was where passports were handed in, ID badges given out and cameras and mobile phones left behind.   Remarkably, the 'hole' itself was as strikingly familiar on the morning of the 8th May 2008 as it was back in 1958.   Although several internal changes had been made and technology had obviously advanced a few light years, there was still an uncanny feeling within those of 101 SU that we could have virtually sat down and carried on with our work from where we left off fifty years ago.   Very emotional.    (Thanks to Brian Walker.)
