Two pilots were killed when their planes collided Sunday during the National Championship Air Races and Air Show in Reno, Nevada, organizers of the event said.

“Around 2:15 p.m. this afternoon, at the conclusion of the T-6 Gold race, upon landing, two planes collided and it has been confirmed that both pilots are deceased,” the Reno Air Racing Association said in a statement posted on Facebook.

In a later statement, organizers identified the two pilots as Nick Macy and Chris Rushing.

“Both expertly skilled pilots and Gold winners in the T-6 Class, Macy piloted Six-Cat and Rushing flew Baron’s Revenge,” the updated statement said. “Families of both pilots have been notified and support services are onsite as they deal with this tragedy.”

No other injuries were reported, it added.

The remainder of the races were canceled, organizers said.

The National Transportation Safety Board said in a statement sent to CNN it is investigating the cause of the crash. The agency, which is leading the probe, identified the two aircraft as a North American T-6G and North American AT-6B, and said they had just completed the race.

“The wreckage of each plane came to rest one-half mile from each other,” NTSB said, adding the wreckage will be taken to an off-site facility for analysis.

Event organizers said they are cooperating with the NTSB, the Federal Aviation Administration and “all local authorities to identify the cause of the accident and ensure that all of our pilots, spectators and volunteers have the necessary support during this time.”

The event, which has been running for more than five decades, prides itself in being an “institution for northern Nevada and aviation enthusiasts from around the world,” according to its website. Over the past decade, the event has brought more than a million spectators and “generated more than $750 million” for the regional economy, according to the site.

This is not the event’s first fatal crash. A pilot was killed last year in a plane crash during a race and In 2011, 11 people were killed and more than 60 others injured when a plane veered out of control and slammed into spectators.(CNN)
