Scandinavian Airlines Flight 686, which used an MD-87 plane carrying 110 people, was headed to Kastrup International Airport, collided on take-off with a Cessna business jet carrying 4. There were no survivors. Wreckage was sent flying into a baggage-handling building, where an additional 4 people were killed.
The accident occurred in thick fog. Investigations showed that the control tower's instructions to the Cessna had not been followed correctly, and the plane had erroneously moved onto the runway.
Linate Airport was operating without a functioning ground radar system at the time, despite having had a system delivered some years beforehand, which had not been fully installed. The new system finally came online a few months later.
