As the search for clues to what caused the disappearance of Air France flight 447 with 228 people on board continues – relatives of the missing passengers say they are ready to take legal action against the airline.Distressed family members say they have a right to be present at the headquarters of the rescue operation. Mariana Paes, a friend of one of the passengers said: “The people are walking inside the hotel and exchanging contacts to be able, in the future, if it becomes necessary, to file a lawsuit or discuss what has to be done. The people (families) want to go to the rescue area.” The families have formed their own commission aimed at closely monitoring the search operation. They want a delegation to be allowed to travel to the islands off the Brazilian coast where the crash investigation is based and where any bodies that may be found will be taken. Paul-Louis Arslanian, Director of the French Air Accident Investigation Bureau urged relatives not to speculate on what might have happened. “Accuracy takes priority,” he said. “Even if the black box flight recorders are found it’s not certain they will provide information relevant to the investigation. Let’s not deal in assumptions, let’s deal in facts, put them all together and see if we can establish a coherent explanation.” Brazilian search coordinators say they have spotted more wreckage including an object, seven metres in diameter and a 20 kilometre-long oil slick.
