The Plane That Wouldn't Talk (Air Crash Investigation - National Geographic)

(Alternative Title: Mixed Signals)

Birgenair Flight 301 was a scheduled Puerto Plata-Gander-Berlin-Frankfurt flight. The Boeing 757-225 on the route, operated by Turkish-managed Birgenair partner Alas Nacionales, crashed. On takeoff, the captain finds that his air speed indicator (ASI) is not reading properly, though the co-pilot's ASI is showing the correct speed. Both pilots become confused and believe that both ASIs are malfunctioning. They lose control of the aircraft and it crashes in the Caribbean Sea shortly after take-off from Puerto Plata's Gregorio Luperón International Airport in the Dominican Republic. All 13 crew members and 176 passengers die.
