you started off claiming that the cone was a moving puff of smoke from a airborne missile
then you changed it to being a jet aircraft firing missiles
now you're saying that something struck the pentagon prior to the major impact
so you're claiming that these "imbeciles" coordinated a double attack on the pentagon in a time frame of less than .5 of a second
there are only two possible explanations
1) you're not very good at photographic interpretation
2) you are an al quaeda agent intent on stirring up trouble for the U.S. Government
which is it ?
