Six Flags Ninja Roller Coaster California was derailed Monday after the roller coaster hit a tree branch at the Six Flags Magic Mountain amusement park. According to CNN, the front car of Six Flags Ninja Roller Coaster California has been dislodged after the branch fell and left four people injured with minor injuries. Day turned to night as nearly two dozen roller coaster enthusiasts were also left suspended 20 to 30 feet in the air for hours due to the Six Flags Ninja Roller Coaster California derailment.

By 8:30 p.m. after being stuck for nearly three hours, the Los Angeles Times reports that the 22 people riding the Six Flags Ninja Roller Coaster California have been evacuated safely. Though suffering only minor injuries, two riders were "transported to a local hospital for precautionary measures," Magic Mountain spokeswoman Sue Carpenter said. 

Jeremy Ead, one of the injured riders from the Six Flags Ninja Roller Coaster California derailment, told KCAL-TV, 'We were going across one turn and all of a sudden a loud noise happened. I ducked down just in time. A hard branch hit me in the head. I was there bleeding from my head, which was a little worse than this.' He reportedly made the statement and pointed towards the gash on his forehead.

In order to evacuate the riders properly from the Six Flags Ninja Roller Coaster California, a specialized urban search-and-rescue team was called in to assist as some riders were not only suspended 20 feet, but 40 feet above ground. According to the Associated Press, the stranded passengers were seen talking to firefighters as the officials tried to free them.

Carpenter explained the Six Flags Ninja Roller Coaster California derailment happened after a tree branch fell on the track and obstructed the train's passage.

The Los Angeles County Fire Department confirmed a total of four people injured from the Six Flags Ninja Roller Coaster California derailment, but only two of the four injured were taken to a nearby hospital.

Los Angeles County Fire Department dispatch supervisor Michael Pittman told KTLA-TV that the branch hit the Six Flags Ninja Roller Coaster California about 5:30 p.m. making it stop. It reportedly took nearly three hours before all 22 riders have been rescued.

Pittmann added that the car was about 20 to 40 feet in the air as rescue workers climbed atop the track and made use of a thick rope to tie the front of the car to the Six Flags Ninja Roller Coaster California track.

Chambers told CNN affiliate KTLA that she 'saw the Ninja go into the trees.' She added, 'It was just a lot of leaf noise and then cracking noises and crashing noises and a lot of screaming.'

Six Flags said in a statement that each park staff was alert throughout the evacuation process.

Meanwhile, Six Flags Magic Mountain said it is inspecting the derailment of the Ninja roller coaster. The Six Flags Ninja Roller Coaster California will reportedly remain closed while inspectors are survey the track and the area.

On Tuesday, the Six Flags Ninja Roller Coaster California derailment instantly took Twitter by storm with people claiming they would never ride a coaster again.

According to the National Post, the Six Flags Ninja Roller Coaster California derailment is the latest in a long line of high-profile roller coaster accidents in previous years.

Last July, Six Flags Over Texas in Arlington shut down the Texas Giant roller coaster after a woman died after getting thrown out of her seat, reports CNN. Although ruled an accident, the woman's family sued both Six Flags and the German company that built the coaster's trains, who both only denied any wrongdoing.

In 2012, another amusement park accident happened at another Southern California amusement park, Knott's Berry Farm. During that time, riders were suspended more than 300 feet and were rescued three hours later. Luckily, nobody got injured from the collapse.

According to the International Association of Amusement Parks and Attractions, 4.3 injuries per million attendees are happened at U.S. fixed-site amusement parks in 2011 alone.

However, such incidents worldwide are reportedly very rare, and experts say that amusement park attendance have only increased over the years.

Six Flags Magic Mountain is reportedly the 18th most popular amusement park in North America, according to the Themed Entertainment Association and AECOM global attractions attendance report. Six Flags Magic Mountain is located in the Valencia area of Santa Clarita, 40 kilometres north of Los Angeles.
