There are some things in this world that humans shall never understand. This is one of them I think. It is said that when god created the earth he made 1000 questions and only 500 answers (Or something like that.) I dont mean to offend anyone by dissing their religion. Perhaps we should just remain in wonder, I mean isnt that more fun than knowing all.
For the conspiracy theorist:
Maybe that reddish light is a glow left over from stealth camoflague. Stealth camoflague works by defracting light around a person therfore rendering him invisible. But because of this defraction of light he also cannot see. (No light reaches his eyes.) So maybe he uses thermal goggles.
