Ramzi Yousef, mastermind along with Khalid Shaikh Mohammed of the 1993 WTC bombing and the Operation Bojinka plots, is in a maximum-security prison, sentenced to hundreds of years of prison time for his plots. However, he can communicate with Gregory Scarpa Jr., a mob figure in the cell next to him. The FBI sets up a sting operation with Scarpa’s cooperation to learn more of what and whom Yousef knows. Scarpa is given a telephone, and he allows Yousef to use it. However, Yousef uses the sting operation for his own ends, communicating with operatives on the outside in code language without giving away their identities. He attempts to find passports to get co-conspirators into the US, and there is some discussion about imminent attacks on US passenger jets. Realizing the scheme has backfired, the FBI terminates the telephone sting in late 1996, but Yousef manages to keep communicating with the outside world for several more months.

Oh, good Lord! I missed hearing about that somehow.
