# 1973 Nantes mid-air collision

The 1973 Nantes mid-air collision occurred when two Spanish airliners travelling to London hit each other over Nantes, France, on 5 March 1973. They were an Iberia McDonnell Douglas DC-9 flying from Palma de Mallorca and a Spantax Convair 990 from Madrid. All 68 people on board the DC-9 were killed. The CV-990 was able to make a successful emergency landing at Cognac – Châteaubernard Air Base.

## Collision

Iberia Flight 504, a scheduled service from Palma de Mallorca, and Spantax flight 400, a charter flight from Madrid, were both traversing France en route to London. They were guided by French military Air Traffic Control as the country's civilian air traffic controllers were on strike. The Iberia DC-9 was due to reach the Nantes VOR point at 12:52 at flight level 290 (29,000 feet [8,839 m]) and the Spantax Convair CV-990 was scheduled to reach it at 13:00 at the same level. Both aircraft had received instructions from Marina sector Air Traffic Control at the French Air Force base in Mont-de-Marsan, who asked them to contact Menhir sector ATC at the French Air Force base in Brest. The Spantax aircraft was on the boundary between the sectors and had difficulty hearing Marina ATC, also receiving no reply to two requests to circle to avoid arriving at the Nantes VOR before 13:00 GMT. The crew decided to start the manoeuvre without ATC authorisation and while in cloud collided with the Iberia DC-9 at 12:52 GMT.
The Iberia DC-9 lost control, exploded, and broke up in mid-air before crashing to the ground. All 61 passengers and seven crew were killed. Forty-seven of the dead were British citizens, including Michael Jeffery, the former manager of The Animals and The Jimi Hendrix Experience.
The Spantax CV-990 managed to land at Cognac – Châteaubernard Air Base with damage to its left wing. A survivor, Betty Barrett, later recounted:
   My father was sitting in the aisle seat, and I was on the right hand side. And I turned around, and he's very British and very stoic, and I said, "Daddy do you think we are going to make it?". He said, "I rather doubt it darling," and pointed to the other wing.
No-one aboard the Spantax flight was injured, and after repairs the aircraft continued to fly for Spantax until 1979.

## Report

The accident was investigated by French air accident body, the Bureau of Enquiry and Analysis for Civil Aviation Safety. Its report identified difficulties in communication between the flight crew of the Convair CV-990 and air traffic control as well as procedural errors from both parties. The crew's unilateral decision to turn the aircraft brought it into the path of the DC-9. ATC had assumed a time-based separation of the two aircraft at the same flight level.

## In popular culture

The event is briefly mentioned in the MSNBC/The Weather Channel documentary series Why Planes Crash, during the first season episode "Collision Course". The episode features an interview with survivor Betty Barrett who shows images of the CV-990's damaged wing after landing.
