A Smoke Angel from Airplane Flares

Explanation: What type of cloud is that? It is not a naturally occurring one. Looking perhaps a bit like a gigantic owl monster, the cloud pictured above resulted from a series of flares released by an air force jet over the Atlantic Ocean in May. The jet that released the flares, a C-17 Globemaster III, is seen on the right. The flares release smoke and the resulting pattern is sometimes known as a smoke angel. The circular eyes of the above smoke angel are caused by air spiraling off the plane's wings and are known as wingtip vortices.

I wonder how a pattern like that is constructed (as in the flight path the aircraft took to make it). Very cool though.

It looks a bit like the Flying Spaghetti Monster.

Here's a video of a C-130 releasing the flares making the smoke angel:
