Hi John!  You have found some very interesting sites.

The last part of the address is wrong; you should do it with:

    http://www.deutsches-museum.de/e_inhalt.htm

With ".../e_inhalt.htm" at the end you will get the index in English;
with ".../inhalt.htm" at the end you will get the index in German.

The Deutsches Museum is a very big technical museum on an island in the
river Isar in Munich.  I visited it 30 years ago.  It was and still is
gigantic; it's possible to spend many days there.
