On Sunday, September 11, 2022, four McQueeney volunteers joined more than 500 other first responders to honor the 343 firefighters who had fallen during the terrorist attacks on the World Trade Center in New York City on 9/11/2001. The first responders climbed the stairs in the Tower of the Americas in Hemisfair Plaza in San Antonio in full rescue gear twice, a height equal to 110 floors and exceeding the height of the Twin Towers that were destroyed in the attacks. Each participant carried a tag bearing the name of a firefighter who perished that day. Members from McQueeney included Chief Michael Wiedner, Assistant Chief Ray Salas, Firefighter/EMT Brant Wilhoit and Lt./EMT Jonathan Dominguez.
