On February 6, 1996, Birgenair Flight 301 was bound for Frankfurt, Germany but crashed shortly after take-off from Puerto Plata Airport in the Dominican Republic into Atlantic Ocean 26 kilometres off-shore. All 176 passengers and 13 crew members were killed on impact. It was found that one of the air speed indicators of the Boeing 757-200 was not working properly due to a mud dauber wasp having made a nest in a pitot tube, confusing the pilots about whether the plane's speed was too fast or too slow.[11] The black box, data recorder pointed to error by the captain, because instead of measuring the air speed through one of the working air speed indicators he continued to use the faulty indicator and did not return to the airport.
