LONGMONT, Colo. — Two small planes collided midair near Denver on Saturday, killing three people, authorities said.
It was unclear what could have caused the crash between the four-seat Cessna 172 and the Sonex Xenos, a homebuilt aluminum lightweight aircraft that seats two.
Nearby residents who heard the crash and rushed outside told CBS affiliate 9News in Denver they were surprised the planes could have collided on such a clear morning.
One of the planes crashed in a field, the other in a grove of trees, near Vance Brand Airport in Longmont, Colorado, about 50 miles north of Denver. Two people were found dead in one wreckage and one person in the other, the Boulder County Sheriff’s Office said.
The Federal Aviation Administration and the National Transportation Safety Board are investigating. The NTSB said a preliminary report would be released in about 15 days.
The collision happened shortly before 9 a.m. Saturday. The identity of the victims was not immediately released.
