A colleague of mine was driving past the plant shortly after the fire broke out.  He was not from the area and he thought to himself that something unusual was clearly going on there.  Obviously, he couldn't assist and didn't stick around to gawk.  He drove on a few miles to his destination in Henderson several miles away. He got out of the car and was staring at the fire when the blast wave rolled into town.  He reported that it "knocked me flat on my ass".  Dang impressive and what a near miss for him!

Video for those who have never seen it:   Long one here:

Thirty years ago on May 4, 1988, the Las Vegas valley was rocked by three massive explosions. A fire that started inside a building at Pacific Engineering and Production Corporation (PEPCO) in Henderson resulted in 3 explosions.

Here is a quick list of interesting facts about the incident:

1. PEPCON produced ammonium perchlorate, which is a chemical found in solid rocket fuel.
2. Because of the Challenger explosion in January 1986, there was a large amount of ammonium pechlorate at the plant at the time.
3. It was the largest domestic, non-nuclear explosion in recorded history at that time, according to NASA.
4. The explosions coule be felt 10 miles away. The two biggest blasts measured 3.0 and 3.5 on the Richter scale at observatories in California and Colorado.
