In May of last year, two men were killed when their Cessna 150 crashed in a field outside Denver, Colorado.

Now, the National Transportation Safety Board has issued its official report – and the agency is saying that selfies likely contributed to the fatal crash.

According to the NTSB, a GoPro recovered near the scene gave clues as to what could have caused the plane to go down in the early morning hours.

“An onboard recording device (GoPro) was found near the wreckage and the files were recovered. Based on the available information, it is likely that the GoPro files were recorded on May 30 and May 31, 2014, with the final GoPro file recorded during the 6-minute flight in the traffic pattern. The accident flight was not recorded. The GoPro recordings revealed that the pilot and various passengers were taking self-photographs with their cell phones and, during the night flight, using the camera’s flash function during the takeoff roll, initial climb, and flight in the traffic pattern,” says the report.

“A postaccident examination of the airplane did not reveal any preimpact anomalies that would have precluded normal operation. Based on the wreckage distribution, which was consistent with a high-speed impact, and the degraded visual reference conditions, it is likely that the pilot experienced spatial disorientation and lost control of the airplane. The evidence is consistent with an aerodynamic stall and subsequent spin into terrain. Based on the evidence of cell phone use during low-altitude maneuvering, including the flight immediately before the accident flight, it is likely that cell phone use during the accident flight distracted the pilot and contributed to the development of spatial disorientation and subsequent loss of control. A review of the pilot’s logbooks did not show that he met the currency requirements for flight in instrument meteorological conditions or night flight with passengers.”

This is the official probable cause for the accident, according to the NTSB:

The pilot’s loss of control and subsequent aerodynamic stall due to spatial disorientation in night instrument meteorological conditions. Contributing to the accident was the pilot’s distraction due to his cell phone use while maneuvering at low-altitude.

Selfie smart, people.
