I remember after the 787 was launched there was a few stories in the press about the batteries catching fire mid-flight, but it turned out the designers and engineers had accounted for that possibility and it wasn't really a big deal. It was a huge deal and the plane was grounded for three month due to those battery fires. Originally the engineers did not account for battery fires and needed to refit a compartment to seal the batteries in case a fire occurs. Luckily it was either on approach, or they could emergency land the plane when the problem occured. A burning lithium battery in a flying plane is one of the worst imaginable scenarios you can encounter during a flight and is a fucking big deal.
