1) Re EMP from conventional explosives.  Digging thru "Effects of Nuclear
Weapons",  A US Governement book, 1962 or later (may come with weapons
effects calculator in the back..) I was surprised to come on the statement
the EMP "... had been observed from conventional explosives....", as well
as the nuclear kind.  NO discussion of mechanisms for EMP from conventional
explosives, however they do create a plasma, and it collapses which is ONE
of the mechanisms for EMP from nukes.

2) There was a query as to how FAE fuel was dispersed without setting it off.
No problem.  It will only burn/explode if there is an oxidizer present.  A
small "burster" placed in the center of a liquid (or even gas) fuel container
spreads the fuel.  If the burster flame front is cool enought to not cause
ignition as the air mixes (and that is just a matter of design...), then the
cloud won't go off.  A seperate, delayed, initiator then provides a seconds
flame front to initiate the explosive.  The initial cloud is simply too
fuel-rich to burn, or explode.
