I took this video at approximately 4:30pm from the 4th floor of Plant 51, a condo complex a few blocks away from the fire. The abandoned building used to house TV station, KNTV, Channel 11. It’s located at 645 Park Avenue on the corner of Park Avenue and S. Montgomery street. Across the street is a firefighter training facility and I’ve heard from neighbors that they would sometimes use the abandoned building for search and rescue training. It was also used by some homeless folks.
