September 11 attacks

The September 11 attacks were four coordinated terror attacks carried out by the terrorist organization Al-Qaeda in September 11, 2001. The attacks involved four hijacked airliners being crashed into major areas of the United States' infrastructure, and caused nearly three thousand deaths.

The global state of alert in the aftermath of the attack was a major factor in the development of Taiga Heavy Industries' F-3 Shinden II. As well, the incident caused a major drop in the sales of the TFJ-01 GoldStar, a business jet manufactured by Taiga.
