patient, and two medical personnel.

Crash blamed on fatigue, training, and distracted texting. Engine ran out of fuel, but the gauges were working properly. Pilot radioed from the hospital that he had 45 minutes worth of

fuel when he only had 30 minutes worth of fuel. Pilot and his friend exchanged 85 private text messages during

a 12-hour shift. Investigators believe the pilot wanted to avoid revealing that he

took off without enough fuel. Autorotation training the pilot received was not representative

of an actual engine failure at cruise speed.
