The shock wave effect created by the truck is achieved through a combination of factors:
1. Engine Power: The Fat Albert is equipped with four powerful jet engines that generate enormous thrust, producing a significant amount of exhaust gas.
2. Thrust Reversal: The truck's jet engines are equipped with thrust reversers. These devices redirect the direction of the exhaust gases forward instead of backward.
3. Flaps and Spoilers: The Fat Albert has a set of flaps and spoilers on its wings. When deployed, these aerodynamic surfaces increase the drag and resistance of the truck, further slowing down its forward momentum.
4. Low Altitude: The truck typically performs this maneuver at a low altitude, which amplifies the effect of the shockwave.
When all of these factors come together, the Fat Albert undergoes a rapid deceleration. The sudden change in velocity creates a powerful shockwave that ripples through the air, generating a thunderous sound and visible vapor condensation that can be seen behind the truck.
