Checkpoint Charlie

I don't know.  It just seemed like a good time to post a reminder.

Shortly after the erection of the Berlin Wall, a standoff occurred between U.S. and Soviet tanks on either side of Checkpoint Charlie. It began on 22 October as a dispute over whether East German guards were authorized to examine the travel documents of a U.S. diplomat passing through to East Berlin. By October 27, 10 Soviet and an equal number of American tanks stood 100 metres apart on either side of the checkpoint. The standoff ended peacefully on October 28.
