Recently, Brad Stewart was scheduled to travel from Ho Chi Minh, Vietnam to Melbourne, Australia.
During the flight, he met an amazing sight.
Shortly after the plane reached cruise speed and the sun set, Stewart spotted hundreds of neon-colored rectangles on the ground.
He was quick to find the camera.
At the time of writing, his video has been viewed 15 million times.

Can someone explain…?
On TikTok, he's asking for help to figure out what the neon-colored rectangles are.
“Someone should be kind enough to help me,” he writes, continuing:
“Can someone explain to me what this is?”
In the comments section, many people are offering their theories about what Stewart saw on Earth.

While most of the comments are joking, there are many who write that they actually know what this is.
Many comment that Stewart photographed the fields where pitahaya, also known as dragon fruit, is grown.
Dragon fruit is widely spread in Asia and Vietnam in particular.
Farmers are using LED lights to extend the plants' growing season, according to the Vietnamese agriculture website Vietnam Agriculture.
This way, the lights can “trick” plants into thinking it's summer, even if it's fall or winter.
This leads to increased yields and profits for farmers.

Many people who watched the stunning video say they were unable to see anything other than confetti in the clip.
“My mind cannot see the dragon groves. Ha, ha. I only see scraps of paper,” one wrote.
“How could this be a damned Dragon Grove?” “It looks like confetti,” another writes.
“You learn something new every day,” someone commented.
