As the mystery of the disappearance of Malaysia Airlines Flight 370 continues, Becky made a visit to City University in London, to learn more about the technical mechanisms behind an aircraft.
Inside an Airbus A320 flight simulator, she spoke to David Stupples, electrical engineer and specialist in radar systems.
Stupples explained the concept of a "satellite handshake", and why the arch that it creates is so huge. He then demonstrated how to turn off the communication inside the cockpit.
In answer to the biggest question on a lot of people’s minds – how the flight could have continued flying undetected – Stupples answered: "If the pilot or the person flying the airplane at that time knew roughly where all the ranges of the radar were he could probably steer a way around the radar coverage. Certainly if he was low enough. What he then would do is to hide himself inside one of the commercial flight corridors because if you come out of those then people will immediately say 'hey, you're an unidentified aircraft'."
