707 & 767 comparisons

I found the 767/707 comparison data on the Boeing website, and the numbers between the two planes are very similar. I have always heard that the 767 was much larger and heavier than the 707. Note, WTC 1 & 2 were meant to be able to withstand a 707 strike travelling at 600 mph. Here are some quotes by the WTC structural engineers:
