‘Ball of fire’: Witnesses describe moment Bentley going over 100 mph crashed at US/Canada border in New York

While many had only surveillance video to form an opinion off of, there were multiple witnesses who saw first hand what really happened.

"He was flying, over 100 miles an hour," a Kitchener, Ontario man who was walking with his wife near the Rainbow Bridge border crossing told WGRZ, noting that the vehicle began "fish-tailing" before striking a fence and becoming a "ball of fire" flying 30 or 40 feet into the air.

"When he hit the fence there was a fire then, but then when he went up again he must have hit the building and there was a big noise," the man added. "He just shot up in the air and you couldn't see nothing but smoke ... I don't think that person is going to survive, their car parts were everywhere."

The two occupants of the vehicle, a couple from western New York state, were pronounced dead at the scene. According to the Daily Mail, the couple was driving a $300,000 white Bentley.

Other witnesses told WKBW the scene that unfolded Wednesday afternoon was "almost like a movie."

"It was fast, but it was almost like time stood still," one man said.

Early assessments have determined that the explosion was not an act of terrorism, but what led up to the crash remains unclear.

"Based on what we know at this moment—and again anything can change—there is no sign of terrorist activity with respect to this crash," New York Governor Kathy Hochul said at a press conference later in the day.

She noted, however, that it had also "not been determined to be an accident," adding, "You don't know whether the driver was intentional in how they drove." Either way, she said she wanted to "make very clear to the public" that it was not a terrorist attack.
