Numerous footage of UFOs were taken from the ground. However, lately the number of videos that have been recorded from airplanes has been increasing.
Whether it is military aircraft or passenger aircraft, the footage shows UFOs passing by or following the aircraft at high speed.
One such recording comes to us from Spain.
These pictures taken from a plane of an alleged UFO flying over the Spanish sky have spread on the net.
Many point to evidence that Earth has been visited by alien craft, but others who are more skeptical claim that it is a weather probe or even a montage.
