of February 18 over northern Kansas was just that, inasmuch as meteorites have been recovered from it." There were found, beginning April 24, first several smaller fragments up to one of 4 1/2 pounds. Then a disturbed spot in a clover field led to the digging up of a piece of some 109 pounds embedded about two feet in the soil. The stone is what is termed as an "achondrite", a technical name for an unusual type of stony meteorite. It is reported to be of a type which will deteriorate rapidly.

A photograph of the trail of the meteor, made by amateur photographer Duane W. Wray of Norton, shows …

Subject: Explosion in the sky near Norcatur, Kans. 4:00 p.m. (MST) February 18, 1948

Purpose: To call attention to some peculiarities in connection, whether coincidental or not

According to an AP bulletin appearing in the Pueblo CHIEFTAIN for February 18, 1948, some object was seen moving eastward across the sky on the late afternoon of February 18th, and when this thing reached a position approximate to Norcatur, Kansas, exploded, or disrupted, or disappeared. The explosi…

It is held by rocketry experts (example, WILLY LEY - see his ROCKETS, p. 192, diagram and note in connection there-with) that it would take about 100 hours for a rocket-craft to negotiate the distance from Earth to Moon.

Prior to its explosion over Norcatur, this object of Feb. 18th was variously reported as a "falling plane", a "jet plane", and a "ball of fire". It is said by some to have left a trail of smoke behind it.

It is the suggestion of this writer that the Army collect and assimilate reports on this object, with a view to determining where it was seen as an object trailing smoke an…

into reports like this one on the explosion over Norcatur and the direction of the object involved.

There is a possibility, however, remote this may seem, that the moon is either inhabited or in use by other than human beings.

It may do not harm to watch the moon for possible arrival of this thing in the quarter at 80 to 100 hours after "its Departure".

Subject: Norcatur, Kans., sky explosion of 18 February, 1948

Purpose: To show a speculation regarding the above phenomenon and another one of earlier date and to call attention to occurrences between the two which have an appearance of relationship whether coincidental or not.

The geographical position of the Norcatur explosion suggests possible linkage with other occurrences happening inside latitudinal limits arbitrarily demarkable between …

horizon of Boise at 3:30 p.m. and another line be drawn from the position of the moon at one hundred hours before the sighting of the Boise object, and projected to the center of the earth, it will be seen that this ten-degrees-altitude and the moon-earth line intersect as a place far above a geographical position considerably to the west of Cape Blance, in the neighborhood of about 700 miles off the coast.

The Boise object in its appearance suggests a rocket-type of craft possibly using reaction blasts to brake itself down for a landing on the earth. The bright point and plumy tail of the de…
