Fireballs
It's easy to assume it was fireworks; after all, it was New Year's Eve.
People in Delta swear that it was not fireworks.
From things falling off of walls to people going outside to see what had happened, Delta locals are now wondering what it could have been.

Impact craters on the moon reveal that the number of asteroid impacts increased dramatically over the last 300 million years. Here, a map of all the impact craters larger than 6 miles (10 kilometers) in diameter and younger than 1 billion years old.
That impact was singularly catastrophic. But, according to a new study published today (Jan. 17) in the journal Science, that smashup was also just one episode in an ongoing spike of gargantuan asteroid impacts bombarding our neck of the solar system. After studying 1 billion years of asteroid craters on the Earth and moon, the study's authors found that the rate of huge asteroid impacts on Earth has nearly tripled in the past 290 million years - and nobody's sure why.
"It's perhaps fair to say it was a date with destiny for the dinosaurs," study co-author Thomas Gernon, associate professor of Earth science at the University of Southampton in the U.K., said in a statement. "Their downfall was somewhat inevitable given the surge of large space rocks colliding with Earth."
At least two dozen people from Maine, New Hampshire and Massachusetts submitted fireball reports though the American Meteor Society's website.
Reports were submitted from 5:20 p.m. to 6:04 p.m., indicating the flash happened at about 5:15 p.m. Most people said it lasted for 3.5 seconds.
Here's a map of the reports filed on AMS:
Martin Mulchinock, from Priddy, near Wells, has been left scratching his head over what the flash and boom was and is wondering whether anyone else heard or saw anything.
The flash and boom could have been seen or heard across Mendip and surrounding areas.
He said: "At approximately 9:55 pm, there was a massive flash in the night sky. A trail was visible but dissipated quickly.
"Roughly five minutes later there was a deep boom which disturbed the grouse. It was pretty dramatic.
The American Meteor Society has so far received 6 reports about this event. If you witnessed it, please fill out this form.
People from all over the Cape, from Hermanus to Franschhoek, Cape Town and all the way to the Swartland, have been talking about the 'massive flash of flight' that appeared suddenly in the twilight sky, The Citizen reports.
According to witnesses, this bright object was followed by a loud bang that shook the ground and rattled houses and windows.
Dan Kloosterman's home security camera in Byron Center was facing in just the right direction to catch the glorious sight at 3:10 a.m. Friday. In Plainfield Township, Christine Ford's security camera got the image from another angle.
The video verifies several reports filed with the Amercian Meteor Society of a fireball meteor that night.
According to the society, a meteor is considered a "fireball" if it is exceptionally bright, or as bright as the planet Venus, in the night sky. The video submitted to 24 Hour News 8 is exceptionally bright.

Some stargazers in the Edmonton area reported seeing a large fireball streak across the sky Thursday night.
Dozens of people took to social media to report that a meteor was spotted around 10:45 p.m. above the Edmonton skyline.
"I was looking out my balcony when I saw a bright ball of light flying through the air," wrote one witness on Reddit.
"It eventually disappeared/broke up mid flight!"
Six people from Edmonton to Crossfield, Alta., filed reports of fireball sightings to the American Meteor Society on Thursday evening.
Jeremiah Hyslop was on his way home to West Kelowna just after midnight when he saw a flash of light streak across the sky.
"At the time I actually thought it was an airplane going down because it was that size and shape," Hyslop said.
When the streak of light quickly grew larger, he knew he was watching a meteor.
