On the History Channel I watched two back to back programs about
Soviet aircraft last Saturday. One was about the copying of the B-29
super fortress to produce the Tu-4 and the other was about the
development of the MiG-15. During the MiG-15 show one of the Russian
designers made a comment something along the lines of "All the
caluulations were made with a slide rule and an abacus." Then he went
on to add "I wonder how many Americans know what an abacus is?" I
guess we could answer him that there are at least a few of us.
