Jim, we had all manner of records from the original UXB guys at school, but it wasn't till I got to R&T and the ATF LEO clearances that I was able to delve into the Bomb data reports.
It was a mish mash of morons and kids and overzealous cops who just watched a Stallone movie as you would imagine, but every so often one came along and just made you whistle!
I know this is thread drift here, but the "Gov't attaché case" was such a piece of artwork, there was NO DOUBT it was a manufactured item. I suspect Israel or US, but it had traits of South African as well. X-ray proof unless you already knew what you were looking for, and when it was recovered (unused thankfully) we had not had TSA yet.
they had machine coiled 75 feet of 7.5 gpf Det Cord under each leather side with a pattern on the outside in the leather so it looked like stitching, the dials for the lock were used for setting the delay time, and it had a chemical battery like a poleroid cart, so until you set time on dial wheels then pull foil strip, it was a s safe as any briefcase. Recovered late 70's if I recall....no idea who made it or how many, but the why is obvious.
Those of you not familiar with Det Cord, 150 of it will take any plane in history out of the sky instantly.
There were others.......
