Large Black Cylinder Flies Above Mountain Lakes Near Guntersville, Alabama

Observed large black cyllindrical craft moving between the mountain ridges above US Hwy 431 as I drove south over the old 2 lane mountain pass at Snug Harbor, just north of the Department of Transportation facility and the Tennessee River Bridge. This was in March 1994 before the highway was four-laned at the turn of the 21st Century.  The object had no wings, tail or any identifying markings.  It looked like a big black railroad gasoline tanker rolling through the sky at low altitude, moving west to east.  It was visible only for a second or two before it disappeared behind the eastern ridge on the left side of the highway.  The object made no noise at all.
Witness indicates that the date of the sighting is approximate.  PD
