The U.S. Bank Tower on the left is the tallest building in Los Angeles, California at 1,018 feet (310m) comprised of 73 stories. I have no idea who currently owns the building which has changed hands several times since construction in 1989.
The building was targeted twice for terrorist attacks. Both attacks were foiled. The original plan for the September 11 attacks included the building according to some reports.
There have been several reports of missiles being launched from the building. Total hogwash.
