a) If there was a Pakistani airlift, our military knew about it. It would not have been possible to run airplanes from Kunduz in November without American permission.
b) Hersch's source says 4,000 to 5,000 people were airlifted. That's 50 to 200 flights.
c) There has been one previous story about this activity. Are we to believe that no one saw or reported 50 to 200 Pakistani flights leaving Kunduz airfield, or that the only people who know about are the Indians (who had no known military observers on the ground)?
d) Hersch's story is simply implausible on the face of it.
The story reads that there was a US established corridor for the Pakistani Air Force to operate within.
50 to 200 flights? The way these group travel, hearded like cattle, its barely 20 flights, if that. Do not exagerate just for the sake of making a point.
