World Trade Center

The World Trade Center was a series of buildings in New York City. The most prominent being the Twin Towers, two massive rectangle buildings that were, at one point, the tallest in the world. At one point, terrorists placed a bomb in the building attempting to blow it up. However, they were unsuccessful. When Spider-Man became Man Spider he kidnapped Punisher and took him to a "nest" in the garage that was damaged by the bomb. Kraven the Hunter managed to smell bomb residue in Man Spider's webbing and tracked him to the garage. He found Punisher and the two attacked Man Spider. They then used a serum developed by Mariah Crawford to return the webslinger to his normal self.

Background
In the real world, on September 11, 2001 terrorists hijaked airplanes, flew two into the Twin Towers destroying them, and murdering about three thousand people. Out of respect for those killed, Kraven's explanation in was removed and it was changed to simply an anonymous garage. Though it creates confusion as to how Kraven was able to track Man Spider.
