A look at three deadly air disasters that were caused by misunderstandings between pilots and air traffic controllers.

Advanced computer graphics, forensic science, eyewitness accounts, interviews with experts, archival footage and re-enactments piece together in great detail the events that led to some of the biggest disasters of modern time.

"X-Ray Mega Airport" uses the latest technology to reveal the inner workings of Frankfurt Airport in Germany. The series employs computer-generated imagery to demonstrate what is underneath the surface of a plane, the internal space of a cargo-carrying truck, and even exposes what goes on in the minds of passengers and crew during a flight. The brain waves of a pilot are documented as he attempts to land an aircraft in crosswinds, and engineers are seen working on an Airbus A380's engine. Other episodes include the operations behind movement of luggage, how the conveyor belt system works and how controllers can single out pieces of luggage among thousands.

To soar through the skies is a dream. Modern technology has allowed human beings to take to the skies and while plane crashes are rare, there's still the issue of near misses. These technological advances are capturing these near misses on camera and cockpit recordings to provide insight as to the terror they can cause. See how pilot errors, technical failures, massive storms and small mistakes can place passengers into life or death situations and the why of these incidents and how to prevent them from reoccurring.

Taking to the sky in an airplane can be dangerous when the weather doesn't cooperate. This documentary series investigates aviation accidents and how the elements contributed to them. Interviews with witnesses and survivors, testimony by experts, and data from the plane's black box aid in exploring each incident. The FAA's case files are used to create animations to diagram what happened before each crash. Fog, haze and hail are some of the weather conditions responsible for the disasters.

This documentary series focuses on extreme construction projects -- be they the biggest, tallest, longest or deepest in the world -- and the machines used to create extraordinary structures. Episodes include the people responsible for the cutting-edge design and engineering of each build, talking about how concept transformed to reality. The processes that go into staffing and operating the modern marvels once they are completed are also covered.
