What the hell. The fog at London’s Gatwick Airport was basically eating up any airplane that was trying to land on the runway. Some of the planes essentially disappeared into the unknown, never to be seen again (they were probably sent around). Others were able to land when the fog cleared up a bit but man, that’s a scary time to be in the air.
Fun fact: modern aircraft are capable of landing themselves in zero visibility. Known as “Autoland”, or Cat III/c, the autopilot acquires guidance data from the Instrument Landing System and a radar altimeter, and flies the plane though the final approach, flare and landing. Gatwick is equipped for this type of approach.
