If you are looking for proof of Alien life and extraterrestrial technology, this video might just be what you are looking for.
The video, taken by a Homeland Security helicopter with infrared, shows two Unidentified flying object in Aguadilla, Puerto Rico on the night of April 25, 2013.
On April the 25th at 21:22 local time (Puerto Rico), the air patrol of the U.S. Customs and Border Protection was making a routine patrol when they encountered a UFO. The object was first seen by the captain then by the operator of the control tower.
The UFO circled the Aguadilla airport and made his way to the ocean. The UFO changed its shape when it approached the ocean.
The Unidentified flying object flew just above the surface of the water before entering the water without being affected by hydrodynamic forces.
Watch the video carefully at 1:24 minutes, the time is located in the upper left corner, when the object in question becomes dark (hot), at that moment another UFO comes out of the ocean and joins the first UFO in their original formation, after this, both submerge controllably into the ocean. Many would say that undoubtedly there is alien technology hidden under the oceans of planet Earth, and this video might just prove to be the best evidence out there.
The video in infrared, was recorded using a MX15 L3 EOIR camera using background IR heat, meaning that objects that are hot or give away energy are shown as dark objects.
