As aircraft go, this one looks like it belongs in a video game or perhaps an alien landscape. Instead, it’s in a hangar in the Netherlands and it never actually takes off.

Anyone peering into a disused F15 hangar at the Cold War-era Soesterberg airbase in The Netherlands might have spotted this bizarre black structure and imagined that it was some kind of secret, high-tech aircraft project. They would have been half correct. The angular behemoth, with its wing-like appendages, is an imposing sight upon the airstrip as it rolls slowly out of Shelter 610.
