Two types of large passenger jets hit the Twin Towers on September 11, 2001: both were Boeing 767 airliners operated on regular U.S. commercial flights.

Quick Scoop: What Kind of Plane Hit the Twin Towers?

To be precise, two different flights struck the World Trade Center:

  • North Tower (WTC 1)
    • Airline: American Airlines
* Flight: Flight 11

* Aircraft: Boeing 767-223ER (a variant of the Boeing 767)
  • South Tower (WTC 2)
    • Airline: United Airlines
* Flight: Flight 175

* Aircraft: Boeing 767 (767-200 series)

Both planes were wide‑body, twin‑engine Boeing 767 jets on transcontinental routes from Boston to Los Angeles, carrying passengers, crew, and large amounts of fuel for long-distance flights. This combination of speed, mass, and fuel load contributed heavily to the scale of damage and fires in the towers.

Why This Detail Still Comes Up in Discussions

On forums and in documentaries, people often ask “what kind of plane hit the Twin Towers” because:

  • The towers were originally analyzed for a possible impact from a Boeing 707 , an older but somewhat similar large jet.
  • The actual attacking aircraft (Boeing 767s) were heavier, faster, and carrying more fuel than what the original design studies assumed, which is frequently cited in technical and engineering discussions about why the buildings eventually collapsed.
  • These specifics are used to counter conspiracy claims by grounding the event in known aircraft types, flight numbers, and impact conditions.

In short: both towers were hit by fully loaded Boeing 767 passenger jets on scheduled U.S. flights, not military planes or cargo aircraft.
