Thanks very much Jammie, aka "R1SmokeEater", for posting these videos.
A busy time for fighting fires, not only in the FDNY, but in so many other cities throughout the U.S.
Things had to change or there wouldn't be much left. For some of these places, entire blocks would be lost due to the heavy fire activity.
Today of course technology has greatly improved the investigations of fires. What an arsonist could get away with during those past years, they can't get away with today.
But these videos are proof of what went on during such a different time.
Some of the stories of other cities besides the FDNY War Years, can be found in the thread here called: "The Other War Years".
