This gets more interesting by the minute: now its 4 helos ?
The seals were from Bagram (in Afghanistan), but the exit was to the Arabian sea- right down the center of the Pakistani country ? Or did they fly back to Afghanistan, fly the length of the country and fly back over pakistan enroute to the Carl Vinson, or make a bee-line to Indian airspace and fly south to the Arabian sea.
I find it hard to believe a Chinook wasn't picked up by Paki air defenses.
