So I guess there was a little bit of a 'bang' after all.
There was no compression wave to hold the critical mass together long enough for a bigger bang. This is totally consistent with what I have been saying. You just don't get it. There was a critical mass of U-235 (not plutonium in this case) that managed to release a lot of radiation and cause some damage to the lab equipment. A small 'bang'. It didn't hurt anyone because they were a quarter mile away. Where are the high explosives? Where is the 'exotic' polonium/beryllium trigger? They aren't there because they aren't needed (for a small 'bang').
That's a ridiculous argument...that just because a few laboratory metal supports were bent...that somehow atomic triggers and precise timing aren't required for a meaningful weapon.
You're grasping for straws in your ill-fated quest to somehow frighten all of the U.S. into sharing your old Y2K bunker with you.
Won't work.
