France is the only country still considering the disappearance of aircraft bearing the number MH370 , Malaysia Airlines. According to Ghyslain Wattrelos, a French engineer who lost his wife and two teenage children in the tragedy, the ill-fated plane carried a number of mysterious goods.

Le Parisien quoted Wattrelos as saying that "on the list there are some contradictory passengers, such as the position of passengers." Besides "a mysterious volume of 89kg" goods were added to the list after the flight took off, along with an overloaded container.

However, the expert did not draw any conclusions. "The information may be incomplete or manipulated. Everything is possible. This will be part of the question for Malaysians," Wattrelos said.

The Malaysian government failed to show why the plane with 239 people from Kuala Lumpur to Beijing disappeared from the radar screen. A vast underwater search in the southern Indian Ocean, which is believed to have crashed, found no trace of the Boeing.

Some fragments , likely belonging to the aircraft, were found off South Africa, Madagascar and Mauritius, but the whereabouts of 239 ill-fated victims remained a mystery.

There are even different contradictory theories regarding the cause of tragedy. One of them said that the Boeing might have been robbed - by a pilot, a passenger or a smuggler. The detection of 89 kg load can prove the following hypothesis.

Philip Baum, editor of the International Aviation Security Journal and aviation security professor, said the possibility that one or more individuals may have boarded a plane while it was landing at the yard. Fly and hide in technical and electronic compartments behind the aircraft to act.
