Terror in the Sky - a closer look at the flying humanoids

I know alot of you love monsterquest from the history channel . Here is their most recent episode looking at the flying humanoids. I am not a huge fan of these objects, i feel some of them are likely fakes but some people swear these sinister objects are real:

Sceptics claim that misidentification explains these creatures, however the mounting evidence says otherwise:
