  • A British F-35B crashed during takeoff from the aircraft carrier HMS Queen Elizabeth in late 2017.
  • An investigation found the accident was caused by an air intake cover that was lodged in the intake.
  • The incident shows that a small problem can have big consequences on a jet like the F-35

Why a US Marine Corps F-35B crashed in South Carolina this week is yet to be determined, but as the crash of a British F-35B two years ago showed, even a simple maintenance error can bring down a $100 million jet.
