A bus "exploded" on I-45 this morning as it headed away from the gulf coast. From news footage and reports, it looks like it was carrying a group of senior citizens.
When WFAA took over the news from GMA at the bottom of the 7 o'clock hour, the in house reporter confirmed there was one dead and then threw it to the on scene reporter. I could have sworn I heard her say there were at least 20 dead.
Update: The Morning News has put the "20 dead" figure on its website.
