That is, until now, as New Atlas gets hands-on with Zeiss's new holographic technology for aircraft. A representative clarified that Zeiss isn't an aircraft manufacturer or an aircraft interior manufacturer. I was told that this was a fully integrated projection system for a Next-Generation Head-Up Display (HUD). Suddenly, I was sitting in a 3D helicopter cockpit, which was obviously chosen to highlight the sort of aircraft the HUD system could be installed in. After that, I was shown a more modest application of holographic technology.
