My daughter and I saw one of these last night at dusk over mid-town St. Louis. Unbelievable. I couldn't believe my daughter noticed it and it took a while for me to find what she was going on about (eleven year olds often say odd things), but there it was, dark and silent with faint lighting on the sides so that it was barely visible. Since it looked kind of small, I'd say it must have been very high, as it disappeared above some high cirrus clouds.

Here I thought it was a 2012 thing, but it seems they've been seen for many years, and sometimes up close.
