United Airlines Flight 175 was a scheduled domestic passenger flight from Logan International Airport, in Boston, Massachusetts, to Los Angeles International Airport, in Los Angeles, California. On September 11, 2001, the Boeing 767-200 operating the route was hijacked by five al-Qaeda terrorists and flown into the South Tower of the World Trade Center in New York City, killing all 65 people aboard and an unconfirmed number in the building's impact zone.

Approximately thirty minutes into the flight, the hijackers forcibly breached the cockpit and overpowered the pilot and first officer, allowing lead hijacker and trained pilot Marwan al-Shehhi to take over the controls. Unlike Flight 11, which turned its transponder off, the aircraft's transponder was visible on New York Center's radar, and the aircraft deviated from the assigned flight path for four minutes before air traffic controllers noticed these changes at 08:51 EDT. They made several unsuccessful attempts to contact the cockpit. Unknown to the hijackers, several passengers and crew aboard made phone calls from the plane to loved ones and provided information about the hijackers and injuries to passengers and crew.

The aircraft crashed into Tower Two (the South Tower) of the World Trade Center at 09:03. The Flight 175 hijacking was coordinated with that of American Airlines Flight 11, which struck the top of Tower One (the North Tower) 17 minutes earlier. The crash of Flight 175 into the South Tower was the only impact seen live on television around the world as it happened. The impact and subsequent fire caused the South Tower to collapse 56 minutes after the crash, resulting in hundreds of additional casualties. During the recovery effort at the World Trade Center site, workers recovered and identified remains from Flight 175 victims (see the Aftermath section below), but many other body fragments could not be identified.
