A pilot's cockpit video capturing a UFO "transforming" mid-air has sparked discussions among conspiracy theorists.
The fascinating clip was recorded somewhere over Texas, US, at 37,000ft last week.
Reddit user "OffshoreAttorney" said he received the footage from his best friend, who works as a pilot for JetBlue Airlines, and posted it on the UFO community.
The 30-second footage shows the panoramic view of bright blue sky and thick layers of clouds rolling in the background.
A white spot appears on the horizon for a few seconds and slowly turns translucent before it disappears behind the clouds.
