Guess they've never seen an airplane shadow moving over the ground from the air.
One of the original printouts from the 26 frame video sequence showing the anomalous object just after it had entered the field of view. It is seen to the lower right of shot just above the crater Konig. It was from these early sequence prints that the elliptical shape became apparent. The rounding effect to the right is cut-off is cut-off from the telescope eyepiece.
this is no shadow,and is near the surface of the moon.
