1. Kansas lost two residents in the September 11 attacks: LeRoy Homer Jr., the co-pilot of United Airlines Flight 93, which crashed in Pennsylvania after passengers fought back against terrorists, and Mark Henson, a New York City firefighter who died while responding to the World Trade Center.

2. After the attacks, a shipping container filled with 17 tons of Kansas limestone was sent to New York City to help rebuild the damaged area around Ground Zero. The limestone was used in the construction of the National September 11 Memorial and Museum.

3. The Patriot Guard Riders, a Kansas-based organization of motorcycle riders who attend military funerals and other events to show respect for fallen soldiers and their families, were founded in response to the September 11 attacks.

4. In the days and weeks following the attacks, Kansas residents came together to offer support and comfort to those affected. One example was the "Kansas Cares" project, in which more than 3,000 boxes filled with personal hygiene items, snacks, and other essentials were sent to New York City to help people in need.

5. The 9/11 attacks also had a significant impact on Kansas aviation. The Federal Aviation Administration (FAA) temporarily grounded all flights in the U.S. after the attacks, leading to the closure of many airports across the country. The impact was felt particularly strongly in Kansas, which is home to several major airports and a large aviation industry. The FAA's decision caused significant economic losses for Kansas airlines, airports, and related businesses.
