96-6049 Airtech CN-235-100M QC (cn C042) US Air Force.
The aircraft is the only one of the type operated by the USAF. It has no official designation. It is believed to be used by the CIA to insert SF personnel at small airfields for covert counter insurgency operations. Could have been linked to the "Maersk Alabama" incident, which had just been "resolved" (Good for you, Yanks) Cool!
