Crash
On 7 December 1983, a Boeing 727 of Iberia (Spain's state airline) registered EC-CFJ, operating Iberia Flight 350, a scheduled flight to Rome's Leonardo da Vinci–Fiumicino Airport, was cleared for take-off from Madrid-Barajas Airport's Runway 01 in conditions of thick fog. At the same time, a DC-9 of Aviaco registered EC-CGS, operating Aviaco Flight 134, was taxiing to the end of the same runway for take-off bound for Santander Airport. As the Boeing 727 rolled along the runway, the crew of the DC-9 accidentally made a wrong turn in the fog and taxied their aircraft onto the runway, into the path of the 727. The crew of the 727 saw the DC-9 and attempted to avoid the collision by rotating their aircraft for lift-off; however, the 727 had not reached flying speed and its rear fuselage struck the DC-9. Both aircraft caught fire and were destroyed; all 42 people on board the DC-9 were killed, while 51 (50 passengers, one crew member) of the 93 on board the Boeing 727 were killed.

Notable victims
Among those killed were Mexican actress Fanny Cano (aboard the Iberia 727) and South African pianist Marc Raubenheimer (aboard the Aviaco DC-9).

Investigation
Investigators found that the Boeing 727 and DC-9 had collided due to the poor visibility at the airport, as well as inadequate signs and markings, which led to the DC-9 entering the runway without clearance as the Boeing 727 was taking off.
