Mayby....BUT:
The towers were struck by hijacked Boeing 767 jet planes, American Airlines Flight 11 and United Airlines Flight 175. A typical Boeing 767 is 180 feet (55 m) long and has a wingspan of 156 feet (48 m), with a capacity of up to 24,000 US gallons (91 m³) of jet fuel. The planes hit the towers at very high speeds.
Flight 11 was traveling roughly 490 mph (790 km/h) when it crashed into the 1 WTC, the north tower;
flight 175 hit 2 WTC, the south tower, at about 590 mph (950 km/h).
buildings had in fact been designed to withstand the impact of the largest airliner of the day, the Boeing 707-320, lost in fog while looking to land. The modeled aircraft weighed 263,000 lb (119 metric tons)
with a flight speed of 180 mph (290 km/h), as in approach and landing.[2]The 767s that hit the towers had a kinetic energy more than seven times greater than the modeled impact. Nonetheless, the impacts alone did not cause the towers to collapse.
And here's a
