Re: there ARE flying black triangles
<I know... I've never seen one.
I have. Anchored above Fort Huachuca, AZ, for most of my year there. It was a surveillance dirigible, spanning a few hundred meters (yeah, big) and used to keep tabs on who was crossing the U.S.-Mexican border, where and when.
That was about 15 years ago and, being an unmanned dirigible, never went anywhere. the only engines were small electric fans that kept the thing pointed in a desired direction. That was the limit of its aerobatics.
It was triangular, and very dark, appearing at night to be completely black,
