The plane which made an emergency landing in Westlake, a Cessna 172RG, was given clearance to depart Santa Monica Airport for Camarillo at 1:53 p.m., Howard Plagens, National Safety Board Senior Air Safety Investigator, said at a press conference, according to NBCLA.
The second plane, a Cessna 172 which later crashed into a Calabasas hillside, had been in an holding pattern above Santa Monica Airport and was given permission to depart the airport heading west at 1:40 p.m., the report said.
"The targets merged at 14:01. One target went down immediately. The other drifted off to the west before dropping off the radar scope," Plagens said, according to NBC.
The investigation in the accident is continuing.

A second body has been found in the wreckage of the single-engine Cessna aircraft that crashed in the Santa Monica Mountains near Las Virgenes Road and Mulholland Highway, investigators announced Tuesday morning.
"There are two bodies that the coroner has confirmed that are deceased amongst the mangled wreckage," said Steve Whitmore, a Los Angeles County Sheriff's Department spokesman.
Whitmore said the two bodies were so badly burned from the crash and ensuing fire that not even their genders could be immediately determined.
The plane appeared to have nose-dive directly into a hillside, creating a crater, Whitmore said.
Investigators with the National Transportation Safety Board were continuing their investigation at the crash site today.
National Transportation Safety Board investigators are currently on the scene of Tuesday's crash resulting from a mid-air collision over the Santa Monica Mountains that killed one person and injured three others, according to a report from the Los Angeles Times.
Following the reported collision, one plane crashed into the mountains; the other aircraft, which carried three people, made a hard landing at the Westlake Golf Course.
Both planes were Cessna 172, one of which departed from Santa Monica Airport for a test flight, according to a report from the FAA.
