The last couple of days the History channel had a show, probably a repeat, on jet
engines. In some of the photos from the Skunk Works in the 1940s, there were at
least two slide rules seen. One was on the drawing table of Johnson and the other was
in the hands of an engineer held so as to show that it was definitely a slide rule. Both
appeared to be K&Es.

Earlier, the History channel repeated a show from last year on the Lufftwaffe and its
airplanes -- especially late in the war. In one of the film clips from one of the aircraft
design institutes in 1943-3 there was a slide rule seen. It was slightly covered but
appeared to be of Darmstadt design which is to be expected I would think.

After the war, the Allies all tried and did have German engineers brought to their
respective countries to try to gain some of the advanced engineering design that the
Germans seemed to have. Some think that the seed for the Airbus came from some of
these aernautical engineers going to France. The US gained rocket knowledge from
von Braun and his associates. I wonder how many of these Darmstadts showed up in
antique stores in Huntsville, El Paso, Dayton and other places.
