It is, how you say in English?, complicated.
Chicago Public Radio - Geopolitics of Drugs: Narcoavión de Guantánamo: "...about the world of private jets and drugs. So let’s start out with what we are allowed to know. On a late Sunday Night last month, an American Gulfstream two private jet, crash-landed into the jungles of Mexico's Yucatan Peninsula. It managed to avoid catching fire, skidding across the jungle floor, and splitting into three pieces. Mexican TV showed images of the plane and its cargo… dozens of “military style” duffel bags containing several metric tons of cocaine.  The reason this made the news is the history of the plane, tail number N987SA…Starting in 2003, the plane made several trips from Washington and Connecticut to Guantanamo Bay. This led to questions of its use by military or intelligence agencies. Since... how many people really fly from Connecticut to Guantanamo?"
KEVIN HALL: The CIA’s confirmed it was used, it was not confirmed now, it was confirmed in earlier reports through the tail numbers
The plane shows up on the list of CIA planes compiled for the EU human rights investigation into the “extraordinary rendition” program. Still, just being used in the program doesn't mean it was ever used to transfer prisoners. Only 2% of the its flights had prisoners on board… the rest were logistical support.
ROOT: You know in some cases, soldiers literally, or you know, CIA interrogators missed starbucks coffee so they would fly in some Starbucks coffee.
But even if the CIA was just using it for coffee runs…it was still a CIA jet. But the big question is: Was it still a CIA jet at the time it crashed full of drugs?
OFFICIAL: I can neither confirm nor deny
Tracing who the last owner was raises more questions than it answers. First: FAA records show the company that had the plane during its
flights sold it on August 30 Guantanamo
The new owner? "Donna Blue Aircraft" a corporation recently registered in....

and was arrested right away for lying about the guns in his bag. Then, he paid several thousand dollars to get his plane back and then flew it to the Canada Azores. He still doesn’t appear to be under investigation for any wrongdoing, despite being the cocaine plane’s owner of record....
Then there is this enticing tidbit:
We’re not allowed to see that yet.
