A former coworker had recommended the tour, as he was a bit of an aviation afficiando having grown up the son of an aeronautical engineer employed by Princeton University that was doing hovercraft research for the US Army (watching the 16 mm "home movies" after work in the shop office was amazing).
So my brother and I and 2 of our friends made the trip... on the way home we stopped by the museum at Aberdeen Proving Ground and also made a detour for Bertha's Muscles in Baltimore.
I don't have the prints of the photos I took, but at the time the Ho 229 was sitting in the same building in about the same position as shown in these shots (click for the full resolution)... Seriously, that building was like a pickers dream for aviation people... how many historically significant aircraft and parts could be crammed into one Butler building?
I must have been in a different building. This was a limited time thing, only open for the weekend IIRC. Where I was had the Japanese Kikka (Me262 knockoff) suspended from the ceiling.
Of course, they also could have shuffled things around in the decade between our respective visits. :)
