WATERTOWN, Wis. (CBS 58) -The National Transportation Safety Board has officially released its report on a Watertown plane crash that killed two people back in 2023. 

Back on June 14 of that year, a single-engine Mooney M20 crashed near the Watertown Municipal Airport, according to the Federal Aviation Administration (FAA). 

That crash killed a pilot and his passenger.

The pilot was set to fly from Watertown Municipal Airport to Manitowish Waters Airport, according to the NTSB. 

But the report shows the pilot lost control of the flight due to "spatial disorientation while operating in instrument meteorological conditions."

That means he was unable to determine his position or motion while flying. 

The report goes on to say that the pilot was on a number of medications to treat his conditions including high blood pressure and sleep apnea, but he had medication is his system that the Federal Aviation Administration prohibits while flying. 

An open prescription for codeine generally is disqualifying for FAA medical certification, although certification may be granted by the FAA in certain cases of infrequent use for acceptable medical conditions. Regardless, Page 15 of 17 CEN23FA239the FAA states that a pilot should not fly after using an opioid like codeine until adequate time has elapsed for the drug to be eliminated from circulation."

A witness the NTSB talked to reported seeing the airplane descend “nose first” into a grass field and wooded area near the soccer fields in Brandt-Quirk Park.

The witness also reported there was a large explosion after the airplane impacted the ground.

The NTSB report goes on to say that the "recorded audio from a digital doorbell camera revealed that the engine was operating at or near 2,500 rpm as the airplane passed abeam the camera’s location about 28 seconds before impact."

According to the pilot's son, the pilot was the only individual who flew the airplane.
