Bruno Le Maire and Michael O'Leary
  • French Finance Minister Bruno Le Maire said he and his family don't like flying on Boeing planes.
  • Ryanair's CEO called him a "stupid politician" and his comments "silly and ill-advised."
  • "Donald Trump is talking rubbish. So is Bruno Le Maire," Michael O'Leary told Politico.

A top French politician's comments about Boeing's safety sparked a provocative response from the planemaker's biggest European customer.
