The fall of the Berlin Wall, part I:
Prior to a scheduled press conference, Communist official Günter Schabowski is handed a note which states vaguely that East Berliners will be allowed to pass into West Berlin if they have proper permission to do so.
Schabowski proceeds read the note to the reporters at the end of the press conference.
He is then asked when the policy will take place; flustered by such a question and unaware of exactly when, given the vagueness of the note, he states it will be effective immediately.
Soon after, word reaches media outlets across Western Germany and gets picked up in East Germany as well. Thousands of people from both sides of the Berlin Wall gather around guards manning checkpoints, demanding that the checkpoints be opened.
