@busillis read Anders Breivek, Ramzi Yousef, and McVeigh. All used ANFO devices and large-ish vehicles

That was my point.

But how did they get the primary explosives

Farming. AN is used in farming. That’s how Breivek attained it in Norway

When I say primary explosive I mean the primer.

Ammonium nitrate is readily available at farm stores

So is sodium nitrate

Urea nitrate

It's what was used in the first world trade center bombing.

I don't think it was a huge amount, if I'd have to guess maybe 50-100kg at most.

Urea can be easily obtained from diesel exhaust fluid...

But AN is highly volatile

It's 35% of the mixture.

Or maybe he was making acetone peroxide on site?

Somebody blew a joggers leg off in New York City a while back with the above compound.

....


The most common route for nearly pure TATP is H2O2/acetone/HCl in 1:1:0.25 molar ratios, using 30% hydrogen peroxide.

Naw, the explosive had a delay, that's pretty telling with ANFO devices.

Due to use of fuses.

(Primarily, there are some that use blasting caps, but I doubt this did, was too delayed.)

How did he get the blasting caps?

Don't think he used them.

I didn't think you could set ANFO with no primary explosive.

That's why there is fuel oil.

That's what amphi is ammonium nitrate and fuel oil it still requires a primary explosive to start the reaction.

Or maybe I don't understand.

I guess in wherever that big Depot of ammonium nitrate that blew up in Lebanon or wherever it was didn't have any primary explosives m

So idk.

Actually, no you may be correct.

If you have a 55 gallon drama ammonium nitrate and fuel oil you have to have it full of blasting caps to make it explode evenly.

I would say the bomber lit a fuse if it was ANFO

That won't work

It might set a diesel fire

Or perhaps in some cases it would explode but I don't think so.

It will

Ramzi/Timothy used one

The bomb was urea nitrate and that itself is a primary explosive.

Then it's likely Tannerite, which is another version of ANFO.

Urea nitrate requires blasting caps.
