Quest for the Invisibles, Infrared UFO's with Ben Emlyn-Jones and Nik Hayes is an independent short film by Neil Geddes-Ward featuring Nik Hayes and myself. See here for the film: https://www.youtube.com/watch?v=_TxfdRoVRCc.
Nik Hayes is a UFOlogist specializing in objects that do not radiate or reflect visible light. They can only be seen with special cameras that can pick up infrared or ultraviolet radiation. He believes that many UFO's might be living creatures of some kind rather than mechanical devices. See: https://www.questfortheinvisibles.co.uk/.
