Source Claims

A meteor exploded over Norcatur, Kansas on February 18, 1948.
Oscar Monnig, of the Texas Observatory, Amateur Astronomy, offers 'tangible proof that a fireball of February 18 over northern Kansas was just that, inasmuch as meteorites have been recovered from it.'
The object seen over Norcatur, Kansas, was described as a 'falling plane', 'jet plane', and 'ball of fire'.
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'.
The explosion over Norcatur, Kansas, could have been a rocket headed for the moon.
If this thing is a rocket of some kind headed for the moon, it might first have been seen as a streak of smoke, then later as a ball of fire, and lastly as a tremendous explosion.
The Norcatur explosion was possibly linked to other occurrences within certain latitudinal limits.
The geographical position of the Norcatur explosion suggests possible linkage with other occurrences happening inside latitudinal limits arbitrarily demarkable between 43° 36' North and 36° 10' North.
The Norcatur incident was a genuine meteorite fall.
As regards the Norcatur, Kansas incident, I remain convinced that, like the Four Corners incident, it was a genuine meteorite fall.
