Moments of tension were experienced on Sunday during the Gunfighter Skies air show in Idaho, when two US Navy military planes collided in the air in front of hundreds of attendees.

The accident occurred about two miles northwest of Mountain Home Air Force Base, where the event was taking place, according to the Idaho Statesman.

Videos spread on social networks show the moment in which the two Boeing EA-18G Growlers collide in mid-flight before rushing towards the ground while expelling columns of black smoke.

All four pilots survived the accident.

After the impact, the four crew members managed to activate the ejection systems and descended by parachute before the astonished gaze of the public.

“We have four good parachutes,” a show host initially announced, as reported by the Idaho Statesman.

Shortly after, organizers confirmed that the four pilots were found alive.

“That is always a positive thing in our world,” said another announcer at the event, who asked attendees to dedicate a prayer for the crews.

Attendees at the show reported seeing sparks in the sky seconds before huge clouds of smoke appeared.

A witness who recorded the incident told NBC News that he heard people shouting that an aircraft had gone down before seeing the four parachutes descending.

“I saw four parachutes coming down and then black smoke appeared,” he said.

Emergency crews and a rescue helicopter were quickly dispatched to the crash site.

Air show canceled after collision

Authorities officially suspended the Mountain Home Air Show following the accident.

Local police asked the public not to approach the air base and confirmed the complete cancellation of the event.

“We understand that many people were looking forward to this spectacle and we appreciate their understanding and cooperation,” authorities said in a statement.

The Gunfighter Skies show had not been held since 2018, the year in which a hang glider pilot died in another accident during the event.

In 2003 there was also an incident when a Thunderbird aircraft crashed, although on that occasion the pilot managed to eject successfully.

The event included aerial demonstrations, displays of military aircraft and presentations by the United States Air Force Thunderbirds, recognized for their precision maneuvers in displays around the world.
