The National Transportation Safety Board has found that texting by a pilot before and during a 2011 medical-helicopter flight in Missouri contributed to its crash.

This is the first time such distractions have been implicated in a fatal commercial-aviation accident.

The crash on August 26, 2011, in Mosby, Missouri, killed Terry Tacoronte, a patient who was being flown from one hospital to another. Pilot James Freudenbert, Randy Bever, a flight nurse, and Chris Frakes, a paramedic, also died. The helicopter was being operated under the name LifeNet.
The distraction from texting helped lead the pilot to take off without enough fuel, the investigative agency found at a hearing in Washington.
The helicopter’s engine stopped after the pilot reported that he had more fuel than was aboard, the NTSB found.
The NTSB documented at least 240 texts sent and received by the pilot during his shift the day of the accident.
