After the Fog

When a wing is generating lift it causes a vortex to form at each wingtip, and sometimes also at the tip of each wing flap. These wingtip vortices persist in the atmosphere long after the aircraft has passed. The reduction in pressure and temperature across each vortex can cause water to condense and make the cores of the wingtip vortices visible. This effect is more common on humid days. Wingtip vortices can sometimes be seen behind the wing flaps of airliners during takeoff and landing…. (source)

Little Su (unfinished symphony — the photo that almost wasn’t)

I almost totally lost this photo (and the few others that I really like from this gorgeous and magical fall-in-Alaska day in which I listened to Gordon Lightfoot’s Don Quixote CD while driving—and singing…. What a breath of fresh air that reminded me of the adventures with my high school friend who is no longer with us. We almost always played Gordon) due to my first major computer download misstep, which also affected the photos of the next day. Ouch! But thankfully I had saved the best images elsewhere.

Where is the sky? We’re supposed to be seeing a light blue sky with thin whispy clouds, which some of its less-exposed brothers and sisters have, which I mistakenly didn’t download before erasing them. Cry, cry. I did save a nearby uncle though, which has the sky. So thanks to miracle of Photoshop, someday this photo should become a complete image with sky.

The symphony may be able to be finished after all!]
