Thanks for the post. Was thinking along the same lines. As you mentioned the “mixture” it brought back to mind the Oklahoma City Penske rental truck bomb that took out most of the Federal Bldng. The mixture was in 55 gal barrel drums.
Fuses were set up to initiate, through shock tubes, 350 pounds of Tovex Blastrite Gel, which would set off the configuration of barrels. There were 13 filled barrels and nine contained ammonium nitrate and nitromethane the other four contained a mixture of ammonium nitrate and diesel fuel. Forty 50-pound bags of ammonium nitrate fertilizer— each barrel weighed nearly 500 lbs. Very destructive as was shown— killing over 168 people including children.
Ya know...that SOB holed up before that here across the Valley where I now live. In a RV campground on old rt 66.
I forgot about that explosion.
