ALTON - It's been 30 years since 21 students lost their lives in a bus crash in Alton. 

On September 21, 1989, a school bus collided with a Dr. Pepper delivery truck on 5 mile line and Bryan road. 

The bus fell into a caliche pit with about 10 feet of water. 

One valley teacher is commemorating that historic day to make sure the memory of the 21 lives lost, goes on.
