Call UFOs Donuts...More Will Take An Interest!
"It's a bird! It's a plane!"
No. It's a SIAD which is an acronym for a supersonic inflatable aerodynamic decelerator. NASA speculates a day may come when a device like the above may be the most efficient way to transport or land robotic equipment on planets like Mars. As it enters the atmosphere the donut inflates causing drag thus a slow down in speed. Some say the SIAD looks like a flying saucer or donut.
"You saw a DONUT/UFO in the sky? What kind? A glazed? A chocolate long? Or just a plain? Which way did it go!" You know they'll want to investigate immediately. :))
