to the evening of June last. O.K., a neighbor and a woman whose from another neighbors, glanced into the sky toward the west, and saw what we thought was make from an airplane. She mentioned that she had never seen that before, and we stopped to look and listen, thinking we would see the plane. But there was no signal, so we kept looking until we saw a tiny object from which the vapor was getting. It was the few days I could see something was with or near the abeam. His only identity was a citizen in the sun. We had watched this one for a few seconds, when from the general direction of the …

Incident #24 -- Weiser, Idaho -- 12 June 1947

There is nothing in the description of this incident that is fatal to the hypothesis that the objects observed were parts of a "double fireball," but any such identification must remain uncertain.

The most convincing element favoring the meteoric hypothesis is the persistent train. Fireballs occasionally leave trains that persist for over an hour.

As far as trajectory is concerned, this is in agreement with that to be expected from a meteor on its way out from the sun (it having gone toward the sun several weeks previously and now being …

Incident #24 -- page 2

The shooting up and down might be dismissed as subjective and illusory, although small bits shooting off from the main meteor could also give this effect.

In spite of all this, this investigator would prefer a terrestrial explanation for the incident.
