The stock price of Airbus fell more than 10% during trading on the Paris stock exchange on December 1st, before narrowing its losses. Prior to this, Airbus had issued a statement saying that a significant number of A320 series aircraft needed to be grounded due to their flight control software being vulnerable to strong sunlight radiation.
