I must watch video of a backdraft in New York this week.

Here you will see FDNY members experience a major backdraft during a 5th alarm fire in a row of stores in the Sunnyside area of queens. (to the best of my knowledge no FDNY members were hurt during this backdraft. 

Here is the link to the video that highlights the smoke explosion: https://www.youtube.com/watch?v=66z7YVwE7n8 

Be SAFE!
