I'm on travel this week in Europe. My first start was Cologne to meet with the gang from the Franhofer Institute and to present plaques to them and the Cologne Fire Department, thanking them for allowing us to participate in the State Archive Building Collapse. Hartmut, Sebastian, and Thorsten came down from Bonn for dinner and a walk by the collapse site, now leveled, waiting the conclusion of lawsuits, new officials, etc. It is hard to believe that it has only been 3 months. Not only has it only been 3 months, but the city had erected a temporary roof (like those used at stadiums) and removed it.
BTW, I was told the oldest, most valuable manuscripts were among the 20% forever lost.
Prof. Thomas Christaller was receiving a prestigious medal, so the timing was bad, but Harmut arranged a "mini-symposia" at the Franhofer Institute with Capt. Rorhle and me giving talks. All of Capt. Rorhle's slides were in English, so despite him talking in German, it was totally fascinating. Perhaps the most fascinating was to see the timeline of events, from getting a call 2 minutes before the collapse throughout the first hours. The flow of information (and mis-information) is apparently the same there as it is in the US-- which really emphasizes the need for emergency informatics.
Prof. Stefan Wrobel attended and my hats off to him and Thomas for an amazing place! It's a lovely combination of old (a castle) and new (the buildings and especially the robotics high bay lab) with an artistic and eco sensibility ("green" roofs).
So looking at the cleared site, similar to the WTC site, it is hard to tell that two people lost their lives there, that a physical connection to the past was lost as well. But given that Cologne appears in some ways defines itself by the bombings from WWII, I suspect every resident can feel the tortured earth and have added it to their long memories.
