Two flashing bright white lights, estimated 300 or more feet apart, that cruised oddly, slowly for 2-3 minutes and suddenly shot down out of sight in an instant. there is no obvious airfield and i have witnessed many planes fly by - though the flyby is infrequent - the planes are distinctively small in appearance. this object (or the lights connected to what i would assume were wing tips or edges of a craft) was massive. hard to tell due to the distance but i would vote ~1000 feet across from light to light. the lights were flashing in the typical style of a standard aircraft: blink, blink, blink. but the lack of any coloration and the distance between the two - clearly attached to a singular craft - was just bizarre. the closer i observed the stranger it became noticing an odd drift from left to right, smooth but with no tilt like an airplane would require. it then seemed to stop moving, paused for a few seconds and rush plummeted directly downward out of sight in an instant. i am well researched on ufo phenomenon and am always interested but have only seen things that are questionable. this was indisputably bizarre and inexplicable.
