Unless the one observer (Pvt Daily) was located "behind" the ridge, the flash could n~t have occurred as high as indicated by paragraphs 3a, 8 and 9b. (As expressed in par 3c, the estimation or an altitude quantity without aome size refer- ence cannot be a:~omplished with any degree or accuracy, even by observers trained in this functio~.) c.~ Pa.~ .-incli:ates tb.at the occurrence was not noted in other e.reaz, and therefore SS~ lJ~al!z~d that ~t must have been at a low altitude. d. Ins,~ficie s~e:ific ~enti~n was made, but it can be presumed that it ~ was not a pistol (o r ~ther tj~e) flare because the observers should have been familiar with them. e. PFC J ohnson said it disappeared oe!1ind a cloud, which may mean beyond the cloud (in dista~ce) as ~ell as above it (in altitude). t. Johnso~ said he couldn't say that the trail was connected with the 1 light; PFC Brown saij tc~ length of the trail grew, faded at one point, and reappeared at another. These descriptio~s are consistent vith a vapor trail appearing at a dis- tance downstream fro::t the source of a heated air stream., and fading as the source passes through a l~cal area where temperature and htwidity are incompatible with vapor formation. g. Par 3k disagrees with Johnson's statement that it moved from his right to left (north t.~ s.Juth ) Johnson appear a to have been particularly observant specific in his repor~. i h. 1be l~inescence of the trail could be due to the low position of the moon; other color reports (par 3e) may provide the best cllle_ to identification of' the source obJect, such as whether it was a ground-launched rocket or missile, or some- 2. The flash as reported was too bright to be associated with afterburner re- light. The magnitude of the flash appears to have been consistent with a flare for night photography. These flares often leave a trail and $ive the appearance of moving at a high velocity. SubJect: (a.e.M .... t Korea Poaalble ID~cat1ona ot A1rc COMM!:RT 1m 2 (contd) ~ or Mlaaile Activities in 3.
