Hypotheses

List of versions containing features matching the eyewitness descriptions or material evidence

Sky lantern

Sky lantern (Chinese lantern, Thai lantern) – flying glowing paper design rice paper stretched over a light wooden frame, bamboo ring burner.

According to the principle of it is similar to the thermal balloon (Montgolfier): the Flame of the burner heats the air inside the lantern to 100-120°C. When heated, the air density becomes smaller, and accordingly with a limited volume and its mass. The air inside the lantern makes it lighter than the air outside, so the flashlight floats in the cold air.

Birds

In connection with the peculiarities of the bird in the photo you can capture the moment when a normal bird will resemble the shape of a "classic" UFO.

The plane/helicopter

Flying machine heavier than air to fly in the atmosphere (and in space (eg. The orbital plane)) that use aerodynamic lift of the airframe to hold yourself in the air (when flying within the atmosphere) and thrust force (propulsion) installations for the maneuvering and compensation for the loss of total mechanical energy to drag.

Rotary wing aircraft, which are necessary for flight lift and thrust generated by one or more rotors driven by a motor or several motors. Differ in maneuverability, ability to hover and almost vertical takeoff.
