Don't know much about the Austin airport incident, JP, but on tonights local news (Dallas/Fort Worth area) there was a story about two freight trains that crashed head-on. It happened in a remote rural area north of the Dallas metroplex, between here and the Oklahoma border. One person dead at news time, one of the trains was carrying diesel fuel.
