LOS ANGELES TIMES, April 11, 1979 

* Wichita Falls, Texas F4 tornado 
* Red River Valley tornado outbreak 
* "Terrible Tuesday" disaster 

The front page has a banner headline announcing: "48 Killed in 'Tornado Alley'" with subhead. (see images) Nice for display.
Complete 1st section only with all 30 pages, very nice condition.

Background: The historical significance of the April 10, 1979 "Terrible Tuesday" outbreak lies in how it fundamentally revolutionized both public safety communication and the science of severe weather meteorology. From a public safety perspective, the tragedy became a tragic textbook study on human behavior during disasters; the high number of fatalities inside vehicles led to a massive, permanent shift in National Weather Service (NWS) safety protocols, which now explicitly instruct people to abandon cars and seek sturdy shelter rather than trying to outrun a tornado. Meteorologically, the outbreak coincided with SESAME (Severe Environmental Storms and Mesoscale Experiment), a major NASA and NOAA field research project. Because the atmosphere was already heavily instrumented with experimental weather balloons, rapid-scan satellites, and early Doppler radar networks, scientists captured an unprecedented volume of high-resolution data on a tornadic supercell from birth to death. The insights gained from analyzing the Red River Valley outbreak directly accelerated the development of modern NEXRAD Doppler radar technology and advanced predictive computer modeling, drastically improving tornado lead times and warning accuracy for future generations.
