Subject: Re: Mexico City Video

I previously posted a preliminary analysis of the Mexico City
Aug. 6, 1997 sighting/video which will be in the next issue of
the MUFON Journal.

I recently received from the MUFON investigator in Mexico City an
aerial survey photo which shows the buildings in the pictures.  I
also got a scaled map.

These have allowed me for the first time to calculate the angular
size of the UFO image and to estimate its distance.   I find that
the UFO was probably a little more than twice the size I used in
the posted paper, i.e., 43 ft vs 20 ft.   Since all the speeds
and accelerations calculated in the article were referenced to
the assumed 20 ft size of the UFO, the new data can be
incorporated by multiplying all the previous numbers by 43/20 or
about 2.   Further analysis combined with witness testimony may
allow for even more precision in determining the distance of the
UFO from the camera.
