Yes, it was built to withstand an aircraft strike, what it WASN'T built to withstand was the intense heat of the jet fuel burning. The heat weakened the trusses and once one floor collapsed, gravity took over and it was a chain reaction. And the reason the both the collapses were similar was because both buildings were designed the same way and were exposed to the same conditions leading to the same failures.
