Independent aviation safety expert David Gleave told the BBC what was now happening to the wreckage.
"They've jacked the aeroplane up so it's on big stands. They've put airbags underneath it and a whole series of railway sleepers, so now they can enter the aircraft and it's relatively safe," he said.
"It's not going to collapse and sag any more. They'll take a look underneath the aircraft.
"They may consider pulling the engines off the aircraft and sending those away to be stripped down and looked at in greater detail.
"They may take the luggage off, they may take the fuel off, in order to make the aeroplane as light as possible to move it."
