Authorities are aware of, and concerned about, the possibility of a suicide attack using a hijacked plane, according to a paper on the threat of terrorism against commercial aviation by Brian Michael Jenkins of the RAND Corporation. “The nightmare of governments is that suicidal terrorists will hijack a commercial airliner and, by killing or replacing its crew, crash into a city or some vital facility,” the paper says. “It has been threatened in at least one case: In 1977, an airliner believed to have been hijacked, crashed, killing all on board. And in 1987, a homicidal, suicidal ex-employee boarded a commercial airliner where he shot his former boss and brought about the crash of the airliner, killing all 44 on board. Fear of such incidents is offered as a powerful argument for immobilizing hijacked aircraft on the ground at the first opportunity and also, some argue, for armoring the flight deck.” The paper asks: “What are we likely to see in the future? Perhaps fewer but deadlier and more sophisticated terrorist hijackings.” [Jenkins, 3/1989, pp. 10-11] The 1987 incident refers to Pacific Southwest Airlines Flight 1771, which is believed to have been hijacked on its way from Los Angeles to San Francisco by a disgruntled former employee. [Time, 12/21/1987] Jenkins will repeat his warning of terrorists possibly using a plane as a weapon in a threat assessment for the New York Port Authority in 1993 (see After February 26, 1993).

After February 26, 1993: Threat Assessments Predict Possibility of Terrorists Crashing Plane into WTC
Following the 1993 World Trade Center bombing (see February 26, 1993), the New York Port Authority asks investigative and security consulting firm Kroll Associates to help design new security measures for the WTC. Kroll’s Deputy Chairman Brian Michael Jenkins leads the analysis of future terrorist threats and how they might be addressed. Assessments conclude that a second terrorist attack against the WTC is probable. Although it is considered unlikely, the possibility of terrorists deliberately flying a plane into the WTC towers is included in the range of possible threats.
