A motorist who barely escaped a helicopter accident on a Sacramento highway has revealed unsettling details of the crash, which has left at least three people in critical condition.

A medical helicopter suddenly descended onto the bustling Highway 50, stretching East from Sacramento towards Nevada near Lake Tahoe, shortly after 7 p.m. local time.

In the immediate aftermath, as many as 15 bystanders rushed to the crash site to help drag victims from the ruins, authorities said.

Authorities confirmed it was a REACH medical helicopter. According to Sacramento Fire, as reported by KCRA, the aircraft was carrying no patients but had a pilot, a nurse, and a paramedic on board.

Captain Justin Sylvia with Sacramento Fire said all three crew members were taken to the hospital with critical injuries. 

Two crew members were found on the roadway, while one was still stuck in the wreckage of the helicopter. 

Davi Bychkoviak, a Sacramento resident who was on his way home from wsorry mork when the tragedy struck, found himself just feet away from the aircraft as it slammed into the highway. 

He told the Daily Mail that in the moments leading up to the disaster, he saw the red helicopter flying close to the ground, prompting him to start filming from his car. 

‘Then just literally, a couple of seconds after, the crash happened, literally five feet next to me,’ he recalled. ‘It was pretty scary.’ 

‘There was no explosion, it was just loud and there was smoke everywhere,’ he went on. 

Bychkoviak’s video shows the doomed aircraft rapidly dropping and colliding with the highway in a matter of seconds. 

The crash sent smoke shooting into the air as the helicopter was smashed into pieces. 

Bychkoviak said he ‘didn’t understand what happened at first,’ but experienced terror once he processed what he had witnessed. ‘That’s the first time I’ve seen something like that.’ 

A flight tracker has indicated that the Airbus H-130 helicopter had departed from the roof of UC Davis Medical Center just minutes before the crash. 

Authorities are still probing the incident and said there are several injured victims.

The Daily Mail has reached out to the California Highway Patrol (CHP) and the Federal Aviation Administration (FAA) for comment. 

A spokesperson for REACH, which is based at McClellan Airport, declined to discuss the crash with The Sacramento Bee. 

Shortly after the crash, Sacramento City Councilmember Lisa Kaplan shared a picture of the crowded highway, urging people to ‘stay off’ the road. Eastbound lanes remain closed for the night, but westbound traffic has resumed. 

In another X post, she sent her thoughts to the victims and first responders: ‘I pray for all in the crash. Thank our officers & all whom pilot for their public service.’ 

Other bone-chilling images and video captured by people stuck in their cars depict the black-smoke filled sky near where the helicopter landed. 

One video, taken by someone stuck on the freeway, shows the chaotic aftermath of the accident, with vehicles slowly inching forward on the road as the smoke shows no signs of letting up.   

A picture taken at the crash site shows investigators standing in front of the ruins. 

The debris from the red helicopter – flipped upside down – is seen scattered across several lanes. 

‘Honestly, I just really hope that everyone survived and everyone is safe,’ Bychkoviak told the Daily Mail.
