The larger plane, the Cessna 340, had one pilot, one passenger, and a dog. All three inside the plane died. Meanwhile, the smaller Cessna 152 only had the pilot onboard. He also died. Nobody else was hurt, as there was no other passenger and nobody was on the ground when the crash happened. The agencies did not release the names of those who died in the incident.

National Transportation Safety Board Looking Into Why the Two Planes Collided

Currently, the FAA and the National Transportation Safety Board are still investigating the circumstances which led to the crash. Several portions of the airport have now been cordoned off for the investigation.

Salazar said that they were also investigating whether or not the weather played a factor in the crash. However, the weather at the time of the crash was clear, with visibility up to 10 miles.

The lack of air traffic control may have also played a factor. The area around the Watsonville Municipal Airport did not have any air traffic control tower, which could help facilitate the safety of the landing procedures and air traffic within the area.

For smaller airports such as the one in Watsonville, the pilots themselves are the ones who clear the airspace and judge their own maneuvers. Pilots only use common traffic advisory frequencies to announce their actions, whether they are coming in to land their plane or going to fly out of the airport.
