But in the case of the Finnish Air Force, the swastika wasn't intended as a symbol of Nazism. It originated as the good luck symbol of the Swedish count Eric Von Rosen, who served Finland at some point during their fight for independence from Russia decades earlier. It had been in use by the Finns since 1918.
However, given the modern connotations associated with that symbol, God knows why they'd continue to use it. If in fact they do.
