Date of sighting: July 12, 2011 and 2009
Location of sighting: Jet above clouds
As always the decision is your's but these seem like legit anomalies to me. I do not think the uploaders have faked any part of these videos, otherwise I wouldn't post them. They were both posted and forgotten about, and the uploaders went on with their routine postings as usual. Not to mention the latter one in the video was posted back in 2009 and has had all of 66 views up until I came across it.
The second clip (IMO), is quite strange indeed and I dont see how it could be a reflection.. It moves quite odd, though, in the way it keeps up with the wing of the plane. Odd indeed hrm, yes, indeed hm. Enjoy!
