1998-04-15 - Murfreesboro, TN - Sphere

while traveling south on I 24 @ 10 miles north of murfreesboro I saw three round silvery bright objects in an equilateral triangle. They did not move but remained motionless. Very bright but looked like large polished silver balls. The most forward of the balls suddenly inflated in size and then they all vanished.

I could not tell the size of the object. They seemed to be within a mile or so. To me they looked @ 3 inches big from the distance I viewed them. I would guess they were ten feet in diameter or larger. The day was partly cloudy. The interstate runs downhill at the point where I noticed them. They remained for @ 5 minutes before the sphere closest to me became larger and then they all disappeared. I was wondering if any one else had seen it out of the many people on the interstate going home. The objects were a good 50-70 ft off the ground. I could not tell if they were lighted or if the sun was reflecting. That is really the only thing from the list below that I saw.
