So that wall stood from 1961 to 1989, and people still tried to leave, even with the shoot to kill orders. Now estimates are between 138 and over 200 East Berliners that were killed trying to cross that border. But over 5,000 were successful. Actually, a few days after the wall went up, we have Corporal Conrad Schumann in this famous photograph kind of hopscotching across the rolls of the barbed wire to get across. In 1964, there were, I think, 57 East Berliners that dug a tunnel underneath the wall. And then from that point forward, there were thousands of people that did other kinds of antics like using mattresses, shooting cables with bow and arrow and scurrying across that way, light planes, hot air balloons. They did pretty much anything they could to get out.
