HAMILTON — A small plane registered to John and Cherril Longhurst of Darby crashed at an airport in San Diego County early Tuesday, killing the two people who were on board and a dog.

Officials have not released the names of the deceased pilot and lone passenger. A second dog that was in the plane survived.

No one on the ground was injured.

A witness told The San Diego Union-Tribune that the single-engine, four-seat Cessna 182 Skylane went down about 6:55 a.m. in an industrial lot after taking off from Gillespie Field, heading west. It made some kind of “throttling” noise, and the pilot tried to return to the airport, but lost power and hit the ground nose first, destroying the front of the plane.

The National Transportation Safety Board and the Federal Aviation Administration are sending investigators to the crash site, according to the Union-Tribune.
