I also remember that one. This video shows the buildup:
At first it is “just” a display of fireworks, the real explosion happens at about 2:18 in that video. I remember another video, where you could literally see the shockwave coming at the camera before it was knocked over.
In Illinois, a fireworks factory blew up each year from 1970 through 1973. I remember seeing the mushroom cloud from the 1972 Orland Park blast, from my school’s playground.
after two weeks straight of nightly amateur fireworls in my neighborhood, followed by three days in a row of big bangers until 3am, this is pure schadenfreude for me…
