UFO sightings have been reported three separate times in as many cities across the world within five days. The recent sightings were reported from Arizona, Melbourne and Manchester. Could these sightings be related to each other?

A pilot and aerospace systems engineer in Arizona, USA on Wednesday saw a glowing strange aircraft in the sky. He was with his girlfriend at the time, and certain that what they saw was nothing ordinary.

"I am an aerospace systems engineer and also a helicopter and commercial airplane pilot. I have never seen an activity in the sky such as this before. I usually try to rule out sightings by making certain they are not bugs, cosmic activity, satellites, aircraft, and so on," the pilot was quoted by Gather.com.

Two sisters, Maggie Waldron and Lorna Hanmore from Manchester, England were reported to have seen a UFO shaped like an iconic character in "Toy Story" on September 22.

Waldron took a photo of her pregnant sister (Hanmore) and the resulting image showed a strange object in the sky background. They were not aware of the sight when the photo was taken, but those who have seen the strange shape on Facebook thought it looked like Buzz Lightyear. The Sun reported the story titled, "UFO floats over pregnant mum." (See the news with photo here.)

On Saturday night, an Aussie man filmed a strange light hovering over Carlton Gardens in Melbourne, Australia. Watch the video clip here or play the embedded media below.

"It was moving like no other flying object that I'm aware exists, and it was displaying amazing patterns of lights that looked something like a light show display in the sky," said the man who only wanted to be named as Tod in the YouTube video description.

What do you think of these recent UFO sightings from three countries across the world? Are they merely coincidental?
