I was aware of the story but as it brought to life in this heartbreaking film really brings home the true pointlessness of war.
You can't help but feel this was something that should never have happened with experienced crew as the war reached its conclusion, especially as it was a daytime raid. There really is nothing friendly about this especially when it came to the 86 children killed during the bombing raid on the Copenhagen Gestapo offices in 1945.
I've never really understood the term friendly fire, it's a term used in the war time when a Allied troops or planes accidentally kills or Injures troops or civilians of an allied country.
