The claim that:
The craft was totally shrouded in infrared light which is invisible to the naked eye.
Is false. Making such absurd claims does not help the credibility of the source nor does the "enhancment" of the imagery.
This is not true either. Image intensifier based night vision devices such as Gen 1, Gen 2, and Gen 3 are sensitive to the visible and near infrared
(short wave infrared) portion of the electromagnetic spectrum. In other words they are sensitive to and amplify the colors of light that we can see
and some other colors next to the red part of the spectrum that we cannot see.
The confusion lies where people have the idea that infrared means thermal imaging. In some cases it does, such as when referring to the long wave
portion of the infrared spectrum. Long wave infrared radiation is emitted by relatively cool objects and can therefore be used for thermal imaging.
Very specialized sensors and optics are required to detect and image long wave infrared radiation. Image intensifier based night vision devices simply
can not be made to do this. The fact that the Gen 3 night vision device used for capturing this footage is only capable of exploiting visible and
short wave infrared light means that the object in the video is either reflecting or creating light from an extremely hot source such as the Sun or
incandescent light bulb elements which have surface temperatures in the thousands of degrees or devices that excite atoms to directly emit photons in
these colors, for example LEDs and flouresent lamps.
