As a middle school kid, on a boy scout trip I saw a stationary "star" gradually brighten, before a triangle of light extended beneath it in the clouds, then faded away the same way it'd appeared, star included. I've always assumed there was a reasonable explanation, this was near Massachusetts around 2006. I'm hoping somebody here may be able to identify my flying object.
