At first i did not paid attention to the wreckage, those really reseble the Comanche - untill a Brazilian site published it www.aereo.jor.br
those images were brough by reuters from one of Pakistain's security force's member few bours after the attack
also, it would explain why they were intercepted by Pakistani airforce, even if they were only 100km from its capital and why the commandos did blow the wreckage after the operation.
in the site they say it can be an MH-60 modified or a completely new aircraft - which i think is the most plausible theory.
do somebody know a stealth transport helicopter?
and finally, why cover an helicopter wreckage?
