Invisible Unmanned Aircraft
MattSparkes writes, "A Minnesota company, VeraTech, has applied for a patent on an unmanned drone that is nearly invisible to the naked eye. The Phantom Sentinel takes advantage of the phenomenon where fast moving objects appear as only a blur, so it fades out of view once it speeds up. This is achieved by rotating the entire craft. The center of gravity is in open air between two of the blade-like wings. There are some videos of a prototype in action on the VeraTech site." The company says you could get usable video of the terrain by processing the images from a spinning camera. One version of the drone is small enough to launch by throwing it like a boomerang. And it folds for travel.
No no no, what you're seeing is the craft edited into the video in the first place. You can't see it normally 'cos it's invisible.
Once I was a four stone apology. Now I am two separate gorillas.
Removing the dog balls from the B-2 bomber reduced its radar return by 42%.
Really.
None of them can see the clouds; The polished wings don't care.
