Tucson Iron & Metal gas axe story and vacancy announcement
2015-09-27
[Breitbart] On September 23, a scrapyard worker at Tucson Iron & Metal was killed after the torch he was using caused a 500-pound bomb to detonate.

The bomb was an MK82, which the General Dynamics website describes as the smallest of the MK80 "tactical" bombs used by the U.S. Air Force & Navy.

According to Tucson News Now, "bomb squad investigators and ordnance experts [said] the explosion involved a highly explosive substance that would normally be used in conjunction with a primer to cause the bomb to explode." The primer that is normally used to cause the bomb to explode had been removed, so the explosion was "significantly smaller than what would've happened" had the bomb exploded in its normal capacity.

Nevertheless, the explosion was large enough to kill 46-year-old Daniel Wright around 12:45 pm when he cut into the bomb.

#4  And to a reporter, anything cylindrical that goes "boom" is obviously a bomb.

#3  ....I had NOT thought of that - they're about the same size, and it would explain the 'partial' explosion thing.

#2  I wonder if instead of cutting into a MK82 he was cutting up a gas cylinder to make a bell. Said cylinder still having acetylene in it. There's a guy a coupled of blocks away from me with bellls like that.

#1  ...Something does not sound right. Let me explain:

*The Mk8X series is filled with Tritonal, a highly stable and heat resistant filler that is engineered to go boom only when we specifically tell it to and then only after a certain series of steps have been performed in a specific fashion.

*Said fashion is thus: When assembling an 8X (BTW, the Mk81 250GP is the smallest of the 8X series, not the 82) you install a booster cup into the fuze well, then install the fuze itself. This is the 'explosive train', a series of progressively larger explosions that will set off the Tritonal filler. Cutting into the bomb body (and I know that we should not speak ill of the dead, but I refuse to believe this guy had no idea what he was looking at) should not have set off the filler - and if it did, and roughly two hundred pounds of filler let go, you wouldn't have anyone around to try and explain what happened. The lethal blast/frag radius for a Mk82 is IIRC two thousand feet, and you don't just get a 'partial' explosion - if any of it goes, it all goes.

* What COLOR was this bomb? If it was green with a yellow band around the nose, that's a live weapon. If it's overall light blue or green with a blue band, that's an inert practice round - but if that was the case, somebody made a horrifying mistake somewhere. I'd also point out that there are stamps on the bomb case indicating what it is (though it's at least understandable that a civilian didn't know to look for those), and it's supposed to be stenciled (at least 1/2" white or yellow letters) as well ('BOMB, MK82 500LB GP'along with two or three more lines indicating where/when it was made). Are we being told that NONE of this was on the bomb in question?

So - what did happen? There's a LOT wrong with this story based on the facts we have, and I will be paying close attention to what comes next.
