That is definitely sky-writing. There used to be a yellow biplane that was regularly sky writing over the Boca Raton, Florida area for years. I’ve watched him make smiley faces just like above many times.

Hey, missed this. Heck, yes, conceded. I haven’t seen any sky-writing over here. They just fly long banners.

It’s skywriting. Jazzroc was wrong in saying that only ice crystal trails can create pendules. I’ve seen skywriting myself with identical pendules.

The circular trail is definitely composed of ice crystals, because it is only an ice crystal trail which can cause visible “pendules” which may be seen in the process of forming.

So whats the story morons?
Which is it? If low altitude “oil” induced “sky writing” looks just like “pendule dripping ice crystals” I’d
say your credibility is ZERO.
Really…

Don, there is no way that the plane changed altitude by 1000 feet before it started the circle and then as it finished it,. it descended a 1000 feet?!OK…I get it. It’s all about how you know it’s true because you know it. 1000 feet (or even MUCH less) could mean the difference of a saturated layer/area and an unsaturated one.

Whatever…
