We saw some very unusual events in the sky that possibly involved normal aircraft and un-normal aircraft.We were driving from MCGehee, AR, to Monticello, AR, when we saw several aircraft in the sky. At first only the "odd objects" were there. Not long after, there were several objects on either side of the "odd objects". These objects appeared to be normal aircraft of some kind, but the ones in the middle (the ones there first) were entirely different, in shape, movement, etc. Maybe I'm crazy......Whatever it was it made enough of an impression on me to make this report.
