An investigation followed the incident. Officials ruled out terrorism although eyewitnesses said that the plane made no apparent attempt to avoid hitting the building. Officials finally suggested that the crash was an apparent suicide. In addition, a note found in the wreckage stated that he voiced support for
Osama bin Laden. But there is no evidence that the teen had any connection with any terror group. A suicide note from Bishop was found stating: Later authorities confiscated a computer from Bishop's parents' house to try to determine a motive for the incident. Moments after the incident, President
George W. Bush was briefly informed about the incident and two unrelated crashes that same day. Bishop's mother filed a $70 million (2002 USD) lawsuit against
Roche Laboratories, who manufacture the acne medication
Accutane. According to the lawsuit claim, the medicine had side effects such as depression and suicidal actions, which the claim stated as the cause of the incident. The suit was dropped on June 26, 2007, by Bishop's mother, who stated she was physically and emotionally unable to continue the action. After the incident took place, numerous security measures were taken. The FAA released a security notice on January 6, the day after the incident. The notice included security of the aircraft and regulations pertaining to underaged flight students. In addition, the
Experimental Aircraft Association and other smaller aircraft organizations proposed more security of flight schools and small aircraft. While authorities stated that the crash was due to an "abuse of trust" rather than a security breach, others argue for the need of increased security due to the simplicity of such actions. ==See also==
