Close But No Cigar

George Elser almost ends WWII and changes the course of history on November 8, 1939.  He manages to blow up the Bürgerbräukeller but Hitler is no longer there.  The former painter of  Viennese souvenir post cards  left the building twenty seven minutes prior to the explosion. Had Hitler not had to catch a train he would certainly been vaporized as the bomb was right behind  the speakers platform, hidden in a hollowed out pillar.

Elser was captured, tried and executed for the act; proving in history and in much else timing is everything.
