And if you did your research, you would know that a 767 isn't built as heavy as the older 707. In other words the 707 would do more damage.<quoted text>
If you actually did your research, he designed the building to withstand a 707 off course coming in for a landing. This would mean the plane was low on fuel and flying slightly above stall speed.
Just like today's cars made from plastic. Ram an older heavier car into an new car and the older car will win.
