It was obvious to me then, that to reinforce, or join a steel "I" beam the gusset plate should be of the same thickness or strength as the "I" beam you are joining otherwise you get the "weak link" syndrome. I was there with John Vigiano at the time and I pointed it out to him. However we are both fireman and not learnard engineers. I don't know if that is the same problem that was just found, but it looks the same to me. See the "WTC Girder is a Key to Collapse Puzzle" The whole place was a crime scene and in my opinion they were in a big hurry to get rid of all the evidance. Photo donated by: John Maher Ret.

FDNY through the years: See dramatic, historic pictures of New York’s Bravest
Take a look back in time to see what the influential melting pot looked like the year you were born and how it has transformed into the visionary, yet raw and real, city that you know and love today. Beams of sunlight streaming through the windows at Grand Central Station. Aerial view of the newly built Empire State Building that stood over Manhattan from 1, feet high—the world's tallest tower until when the World Trade Center took the title. Construction workers eat their lunch atop a steel beam, feet above the ground, at the building site of the RCA Building in Rockefeller Center.
