Should William Potts, an American fugitive living in Cuba, ever set foot in the United States again, he faces an indictment for airplane hijacking and a potentially lengthy prison term.
So why is Potts now battling to return to the same country that wants to imprison him?
In 1984, Potts hijacked a Piedmont Airlines passenger plane bound for Miami with 56 people aboard.
A Black Panther and self-styled revolutionary, Potts dreamed of receiving military training in Cuba that he could use to overthrow the United States government.
But first, the New York native had to find a way to get to the island.
Potts' solution was to smuggle a .25-caliber pistol inside a fake cast on his arm.
The handgun set off the metal detectors at Newark Airport, but all Potts had to do was flash his cast and an easy smile to breeze past security.
After the plane took off, Potts went to bathroom, where he ditched the phony cast and put on what he calls his "Black Panther costume" of dark clothes and combat boots. He walked to the back of the airplane with the pistol in hand.
A flight attendant told him to retake his seat, Potts said, but her eyes grew wide as she saw his changed demeanor and clothing.
Potts gave her a note ordering the pilot to fly the plane to Cuba.
Over the plane's telephone system, the pilot tried to convince Potts to end the hijacking.
"I had to be forceful with him," Potts remembered. "I tell him, if we don't go to Cuba, this plane is going down. We are going to hell or Cuba."
As the plane crossed the bright blue water and the coastline and palm trees came into view, Potts still wasn't sure he was over Cuba.
"I had them go low and circle around," he said. "I was looking for McDonald's and Coca-Cola and propaganda like that. I didn't see any of it, so I figured we must be here."
The plane landed in Havana, but Potts did not get the welcome he expected from his fellow revolutionaries.
After years of hijackings to the island, the Cubans put hijackers like him on trial.
Authorities told Potts that Fidel Castro's government was no longer involved in spreading armed revolution abroad.
"In a Machiavellian sense, the Cubans changed," he said. "They simply changed. They used to do it, and now they don't do it."
Authorities offered to let Potts return with the plane he hijacked to the United States, where air piracy charges awaited him.
Potts said he would face trial in Cuba.
"I thought I had won the case, and they gave me 15 years," Potts said, recalling his brief court proceedings in Cuba. "I didn't even know what 15 was in Spanish. And they said 'quince.' I said, what is 'quince?' and my translator said 15 years. And I said, '15 years for who?' And they said, '15 years for you.' "
Even though he was sent to one of Cuba's toughest prisons, where he regularly battled with other inmates and the guards, Potts never lost faith in the same revolution that had become his jailer.
"If you are not able to suffer for the cause, you are just a play revolutionary," Potts said.
Potts served his time -- 13½ years in prison and the rest under supervised release -- and tried to fit into Cuban society with the pidgin Spanish he learned in prison.
His first marriage, to a Cuban, didn't work out.
