A unique and jaw-dropping occurrence that took place in the Canadian sky has hit the newsstand. Rendering viewers in instantaneous jolt, the happening was one-off and had a chilling effect.

On Oct. 4, the Toronto Police and Fire Services received countless calls as the Canadian night skies were lit by a gigantic ball of fire, which was assumed to be a possible plane crash.

Other than that, the American Meteor Society also received more than 700 calls as observers were not only from Ontario, but also from Delaware, New York, New Jersey, Maryland, Michigan, Pennsylvania and Virginia, reports the Tech Times.

The dwellers of Canada and the eastern United States were able to witness the magnificent phenomenon. The incident took place at 10:36 p.m. with eyewitnesses promptly reported the sightings.

According to the American Meteor Society, "Toronto police and fire services received multiple calls about a 'plane crashing onto the Toronto Harbour,' but luckily it was just a fireball in the night sky," the site reads.

"The preliminary estimated trajectory plotted from the witness reports shows the meteor was travelling approximately from the South to the North and ended its flight south of Cameron, NY."

Some of the reports also pointed to the possibility of a sonic boom, which can be heard within a 50-mile radius of the place where the unusual fireball was sighted. Mike Hankey, the operations manager for the American Meteor Society has placed this jaw-dropping scenario in the 'top ten events of the year'.

"To have that echoing sound means it has to get pretty close to the surface. It penetrated the Earth's atmosphere deep enough to create a sonic boom," said Hankey according to The Washington Post.

What viewers witnessed was an epic showdown of a meteor from the Orionids shower, which are known to be quick and very flashy and are formed from the debris of Halley's comment, maintains NASA. The meteor shower commenced this Tuesday and will remain active till Nov. 14.

Some people said what they saw persisted up to 5 seconds, while another said a "huge bang" accompanied the sighting, disturbing the birds at a farm in Pennsylvania.

Interested inhabitants can witness the peak activity on Oct. 21 and 22 with up to 20 meteors per hour.
