America's Secret Silent Stealth Helicopter in Pakistan
I am sure that the US Navy Seals and the planners of the Osama Bin Laden raid that killed the terrorist did not plan on losing one of America's secret stealth aircraft- this time, the never before seen stealth helicopter based on the Blackhawk.
They did not expect that the warm air over the landing zone in Osama Bin Laden's area which caused instability, enough to warrant the US Seals in blowing it up with all of its sensitive and secret hardware.
The use of the stealth chopper is why Pakistan never saw it on the radar nor why the signature of a helicopter was never heard. The difference in sound alone makes it clear it was used. The stealth helicopter can be barely heard and if you do hear it, one does not think it is a helicopter. The special adhesives and alloys used on the body as well as the angular body make it hard to track using a radar.
Now, not only Pakistan and China will be studying the pieces found and carted off.
