Every time a plane crashes, the world takes notice, and so do the experts whose job it is to figure out what happened. Air Crash Investigation uncovers the truth behind the most legendary aviation disasters, and every episode features eyewitness accounts, captivating reenactments, state-of-the-art CGI, and interviews with the investigators who ultimately determined what went wrong. On this bonus season of Air Crash Investigation, every episode examines multiple cases under a central theme: Rookie Errors reveals the minor mistakes behind some of the worst-ever airline disasters; Collision Course follows the scramble to prevent yet another midair impact; and, on Fuel Failures, a mysterious trail of clues ultimately leads to the fuel tank.
