The amount of visible or at least noticeable NO2 varies greatly
with the exact oxygen balance. One sees the clearest orange-brown
vapor from the venting of underground shots in wet conditions. 
Surface shots always produce a great cloud of dust into which
NO2 can blend to simply look like more dust, especially in
Oklahoma, where dust storms look like NO2 gas attacks. Many
times, NO2 is not even visible from clean surface shots.

The number of events recorded by seismometers is a highly debated
topic among the cognoscenti. There is no really persuasive evidence 
for more than one blast, (at least that I have seen). I've
also listened to the two tape recordings of the event from near
and far. Some say they hear two events; I hear only one.

If the explosive had been a fuel-air mix, there would have been no

Just who were these "targeted" personnel and how do we know
they were targeted?  Who targeted them? Neither McVeigh nor any
hypothetical "insiders" have have yet testified on this subject.  

Uncle Al, it is a big grin to learn that you are a conspiracy buff.
If you find any real evidence for any of the above disputed 
opinions, please let me know. I like a good conspiracy just as well 
as the next guy :). Maybe we'll get some more facts on which to
base our theories from the criminal trial (in April?).
