A plane cherished by its pilots and adored by the public: How the Spitfire became a symbol of national defiance and turned what could of been Britain’s darkest hour into its finest
Mail Online, January 16, 2018
‘Could of’ and ‘would of’ are among the clearest signs of ignorance. This is all the worse because the intro of the story has the correct ‘could have’:
A revolutionary aircraft that transformed the capability of the RAF, the Spitfire rightly became a symbol of national defiance, turning what could have been Britain’s darkest hour into our finest.
This suggests to me either that someone is incapable of copying the phrase ‘could have’ or thought he or she knew better. Either way it’s pathetic.
