There was no fog over Munich the night of 8th November 1939, leading Hitler to speak for longer and take the plane, rather than leave earlier to take the train. In other words, Georg Elser's plot comes off.
Adolf Hitler was nervous. He wanted to be back in Berlin to keep the war under control, but he was duty-bound (and propaganda-bound) to observe the anniversary of the Beer Hall Putsch. Thankfully, the fog that had been hovering over Munich had dissipated, and the plane was waiting to leave as soon as he finished his speech.
At 9:19 p.m, he was in full, horrifying rhetorical flow, and witnesses recount that at that very moment, he was whipping up the crowd against Neville Chamberlain, the British Prime Minister.
At 9:20 p.m exactly, a bomb ripped through the Buergerbraeukeller, killing 33 people, including Adolf Hitler.
