The '93 World Trade Center Bombing

In the 1993 World Trade Center bombing (February 26, 1993) a car bomb was detonated by Arab terrorists in the underground parking garage below Tower One of the World Trade Center in New York City. The 1,500-lb (680 kg) urea nitrate-fuel oil device killed six and injured 1,042 people. It was intended to devastate the foundation of the North Tower, causing it to collapse onto its twin.

Allegations of FBI foreknowledge...
In the course of the trial it was revealed that the FBI had an informant, a former Egyptian army officer named Emad A. Salem. Salem claims to have informed the FBI of the plot to bomb the towers as early as February 6, 1992. Salem's role as informant allowed the FBI to quickly pinpoint the conspirators out of the hundreds of possible suspects.
Salem, initially believing that this was to be a sting operation, claimed that the FBI's original plan was for Salem to supply the conspirators with a harmless powder instead of actual explosive to build their bomb, but that the FBI chose to use him for other purposes instead. He secretly recorded hundreds of hours of telephone conversations with his FBI handlers; reported by Ralph Blumenthal in the New York Times, Oct. 28, 1993, secton A,Page 1. Those tapes were provided to defense lawyers, although they were not used in the trial. Salem also mentions in his testimony Operation Bojinka, a plot by the "Blind Sheikh" Omar Abdul-Rahman and his nephew, Ramzi Yousef, to, among other things, fly about 12 hijacked airplanes into prominent US buildings. They were subsequently convicted of "seditious conspiracy" in connection with the Bojinka Plot. In December 1993, James M. Fox, the head of the FBI's New York Office, denied that the FBI had any foreknowledge of the attacks.

The 1993 WTC sting operation was depicted as a false flag operation and was a plot device for the 1996 movie The Long Kiss Goodnight with Geena Davis and Samuel L. Jackson.
The main character played by Geena Davis has amnesia and has no memory of her past. She hires wisecracking private investigator Mitch Henessey (Samuel L. Jackson) to help her find the truth about her past. She discovers she was an assassin for the CIA who went missing eight years ago. And that her former boss at the CIA has allied with a terrorist in a false flag plot to detonate a chemical bomb in downtown Niagara Falls, New York, frame Islamic terrorists for the crime and thus secure more funding. She and Mitch set out to thwart the plot and rescue her young daughter from the clutches of the terrorists.
