Alaska Airlines 261 nosedives into the Pacific leaving investigators stumped . A rare storm and a deadly design flaw intersect cause American Eagle 4184 to fall from the sky. And, investigators suspect a fatal flaw in the Boeing 737.

Fight to the Finish

S23 E2

Three flight crews face impossible odds: a Boeing 707 loses engines over the Alps as fire spreads, Air Astana 1388 goes out of control over Portugal, and a bomb on PA 434 severs control cables and blasts a hole in the fuselage.

Bad Data

S23 E3

A billion-dollar Stealth Bomber crashes at a U.S. Air Force base-the costliest aviation disaster ever. Bad data misleads a charter flight into a Portuguese mountain, and conflicting alarms send a cutting-edge jetliner plunging into the Atlantic.

Landing Hazards

S23 E4

Martinair 495 crashes on a rain-soaked runway in Portugal, showing how weather can doom a landing. American 1572 hits a storm and loses both engines amid a tower shutdown. And crosswinds challenge an Air France crew already halfway down the runway.

Training Ignored

S23 E5

Kobe Bryant dies when a high-tech helicopter crashes on a routine L.A. route-training ignored with deadly results. In Missouri, cockpit chatter dooms Corporate 5966, and in Lexington, a twin-engine jet crashes after taking off from the wrong runway.

Reckless Approaches

S23 E6

A twin-engine jet slams into an Ohio apartment building in a tragic perfect storm, raising questions about speed, power, and fatigue. A turboprop crash exposes an industry-wide issue, and at Guantanamo Bay, a cargo plane goes down near the Cuban border.
