Huge Explosion and Shockwave
See part 2 here:  https://youtu.be/SgvDkzy2bCM

High Definition video showing thermal disposal of a C4 Trident I first stage rocket motor in Utah.  This rocket motor contains approximately 38,000 pounds of HD 1.1 propellant (this means it has the potential to detonate and create a large shockwave).  If you watch closely you will see a shadow of the shockwave move across the ground before it hits the camera.  Turn up the sound and enjoy.
The video shows a controlled detonation of explosives in a remote desert environment. The danger is clearly the massive explosion itself, which generates a huge fireball and shockwave, sending debris flying into the air. There is no visible safety equipment being worn by the people observing the explosion in the distance, suggesting they are relying on their distance from the blast for safety. The individuals are likely professionals who have planned and executed the detonation. While no one is seen directly affected by the explosion in the video, the potential aftermath could involve injuries from flying debris, burns, and hearing damage if anyone were too close to the blast.
