Building a bomb requires experience in physics, chemistry and mechanical design. He has part of the credentials. There really isn't sufficient information. Nichols and McVeigh "experimented" with alternative forms of energy too...55 gallon drum full of ammonium nitrate and diesel.
Thanks Myrddin.
Something about the way that's worded bothers me.
As a person who knows nothing about you-know-what-making...
I took it to mean that it wasn't an ammonium nitrate bomb he was peddling. One of the articles stated he was offering a 'big' bomb.
Dirty Bomb?
Hopefully, we'll learn more about it soon.
