Texas "Fireball"

Kathy witnessed the widely reported "fireball" over Texas around 11AM this morning. She was northbound on I-35 near Georgetown and described a persistent cloud created by the hyperbolic shaped, metallic object (this appearance was probably a result of a shockwave created by a meteor bouncing off the atmosphere). The cloud lingered for about an hour. She drove directly underneath the cloud which appeared to be centered over Waco.
