I got to see the FDNY in action in my East Village apartment building a decade back after a neighbor's boyfriend set her place on fire. We locked our door and got it popped and it was amazing how quickly and efficiently they took out doors, windows, ceilings and floors as needed to control the fire and get the smoke out. They definitely knew their business and we were back in our 300 sq ft 6-floor walk-up in no time!
Thanks once again, FDNY!
