A helicopter was down in the Osama raid. It is obviously that people try to ‘hide’ it. Though nowadays, nothing can escape the media easily though this project did quite a good job until this event.
My first impression of this stealth helicopter is that it looks so shabby. However, it seems worked for not seen by Pakistani defenses.
I hope further info could be revealed. At the moment, I have made a guesswork depending on what I can achieve now.
