I was just wondering because about 5 years ago I saw something near a local hill that I simply can't explain.
It was about 2am, I wasn't intoxicated in any way, but I saw what I at first thought was a Harrier jump jet, because it was vaguely plane shaped and was hovering, after a minute or so I realised it couldn't be one of those becuse I was startled by an owl hooting which made me notice how quiet the craft was, it also made me notice that it was too triangular to be any aircraft I'd ever heard about.
It disappeared after another minute, which wasn't anything extraordinary as I was still about half a mile away and nowhere near the top of the hill, but ever since, I've wondered if this was a 'secret' new warplane, maybe something more, or possibly I was just knackered from a hard work shift.
