The next day, an explosive ordnance disposal team arrived to pick through the wreckage and found unexploded pieces of a missile casing that could only belong to a Stinger missile.
Lodged in the right nacelle, they found one fragment that contained an entire serial number.
The investigation took time. Arms were twisted, noses put out of joint. But when the results came back, they were stunning: The Stinger tracked back to a lot that had been signed out by the CIA recently, not during the anti-Soviet jihad.
Reports of the Stinger reached the highest echelons of the US command in Afghanistan and became a source of intense speculation, but no action.
Everyone knew the war was winding down. Revealing that the Taliban had US-made Stingers risked demoralizing coalition troops. Because there were no coalition casualties, government officials made no public announcement of the attack.
My sources in the US Special Operations community believe the Stinger fired against the Chinook was part of the same lot the CIA turned over to the Qataris in early 2011, weapons Hillary Rodham Clinton’s State Department intended for anti-Khadafy forces in Libya.
They believe the Qataris delivered between 50 and 60 of those same Stingers to the Taliban in early 2012, and an additional 200 SA-24 Igla-S surface-to-air missiles.
