Birgenair Flight 301 was a flight chartered by Turkish-managed Birgenair partner Alas Nacionales ("National Wings") from Puerto Plata in the Dominican Republic to Frankfurt, Germany, via Gander, Canada, and Berlin, Germany. On 6 February 1996, the Boeing 757–225 operating the route crashed shortly after take-off from Puerto Plata's Gregorio Luperón International Airport. There were no survivors. The cause was a pitot tube that investigators believe was blocked by a wasp nest that was built inside it.
