Oval UFO paces occupants in automobile for 5 minutes on major highway

My Father, an Electronics Technician from Booneville, Ms. was traveling by auto to Meridian, Ms. on business with 2 colleagues when they observed an oval craft, silver in color, with a dome underneath, as they traveled south on Hwy. 45 between Okolona and West Point, Ms. The craft had portholes in the upper and lower parts, and paced them on the west side of the road for about 5 minutes, before disappearing from sight. These men were astounded to see such a craft.
