it never did. Only two planes hit the WTC.
2 planes hit the North and South towers of the WTC and one "plane" hit the pentagon. There was a fourth plane but it "crashed" in a Pennsylvania field. This happened in NY!
The northern WTC tower, then southern WTC tower, then Pentagon and the fourth plane crashed when the patriots inside killed the terrorists but couldn't fly the plane.

Only one plane hit the Pentagon in the September 11th attacks. American Airlines Flight 77 hit the Pentagon at 9:37 AM EST. There were four planes involved in the attacks, including Flight 77. American Airlines Flight 11 crashed into the World Trade Center's North Tower (1 WTC) at 8:46 AM EST. United Airlines Flight 175 crashed into the World Trade Center's South Tower (2 WTC) at 9:03 AM. The fourth flight involved was United Airlines Flight 93 which crashed into a field near Shanksville, Pennsylvania at 10:03 AM EST.
United Airlines Flight 175 was a Boeing 767-223, The same aircraft as the first plane who hit the north tower of the WTC, which was American Airlines Flight 11.
While there is a wide range of possible explanations for the collapse of the South Tower (2 WTC) before the North (1 WTC), it is believed that the lower impact of the plane on the tower (a full 15 stories under the same point on 1 WTC) and the passing of shrapnel and parts of the plane through three of four floor beams weakened the structure at an accelerated rate and brought 2 WTC down before its counterpart.
