Minus any corroborating information, I'd guess this is a hoax. Sounds like nonsense to me.

The light gray colord craft, with no apparent "seams" or rivet patterns visible, was estimated by onlookers to be approximately the size of a small airliner, or light transport aircraft, and traveling at speeds in excess of Mach 2 (twice the speed of sound)

I would not expect to see seams or rivet patterns on an aircraft flying at mach 2. Sounds like a hoax to me.
