Giant UFO near the international space station

An impressive video of an UFO filmed near the ISS:

Of course, this video can be a hoax. I found a discussion of this video at a forum, and most discussers there assume that this is a hoax:

I suppose, currently we are unable to judge whether this video is real or it is a hoax (or maybe a lens flare/internal reflection). To make this judgment, we need NASA to answer 2 questions:

1) Is the youtube video original (if no – then it is a hoax)?
2) What did locators see?

But NASA doesn’t want to work with this, because if they give a positive answer to the first question, they will need to thoroughly investigate what could fly there (maybe a space garbage, etc). If the answer for this question is no, many people will appear who will state that the youtube video is real, and the “official” video was edited by NASA. So, any answer will produce only trouble. Nothing can be proved. So this video should not be considered as a proof, but simply as a nice illustration.
