 at the time of year involved would tend to produce a yellow glow. Another possible explanation is found in the exhausts of the engines which, with the airplane descending under power, would probably emit fairly steady flames resulting in an appreciable amount of light or glow when the airplane approached the ground. The third possibility is suggested by a fairly common experience in which the sudden appearance of a bright light creates the impression that the light existed prior to the actual occurrence. Thus, it is not unreasonable to suppose that the impressions of the witnesses with respect to a glow or flash of light may have been the result of the intense light caused by the subsequent fire.

The preponderance of evidence indicates that there was no fire during flight.

The possibility of sabotage has, of course, been considered and explored, but thus far no evidence pointing with any degree of probability to sabotage has been discovered. Investigation of this possibility, as well as others, however, will be continued.
