An Army training exercise in Fort Campbell turns to tragedy when two helicopters collide and crash. The Blackhawk's rear rotors hit and we talk to the soldiers who survive and their commanding officer. One of the most terrifying bank robberies in history. Two men, dressed in full boy armor open fire with automatic weapons on the Los Angeles Police Department. Their rein of terror last 44 minutes, and leaves several officers lying in their own blood. Shockwave takes you inside the panic, showing you the actually body armor worn by the bank robbers, the guns they used, the police cars riddled by their bullets and we talk to the cops who brought them down. A television reporter and cameraman are caught in a catastrophe. A new outdoor structure is about to be unveiled as the centerpiece of a huge park in Stockton, California. But just as the finishing touches are being put on, a cable snaps, the structure collapses, and the newsmen are sent running for their lives. A high speed chase comes to a crashing stop at a gas station in Manning, South Carolina. The runaway driver slams into the gas pump, his car erupts into a fireball and it's all caught on the cops dashboard camera. A para-glider is heading straight toward disaster. He steers into live power-lines with more than two hundred volts of electricity surging thru them. That's enough to fry an average sized man with a single jolt. Rescuers rush in, but one wrong move and they could get zapped.
