> When Herrhausen's motorcade approached the attack site, the lookout waited for the lead car to pass by the bike, then radioed to the terrorist in the bushes who quickly activated the beam. Herrhausen's vehicle broke the beam which triggered the electronic detonator in the bomb. The front of Herrhausen's car broke the beam at the precise moment the back right seat, where Herrhausen was sitting, was directly across from the bomb. The force of the explosion was aimed at where Herrhausen was sitting. The bomb was placed on a child's bike to match the height of the back right door of the armored vehicle. To develop this attack, the terrorists had to compute the speed of the car, the length of the car, and the height of the back right door. As his car passed the bike, at 8:34 a.m., the bike exploded and some 22 pounds of TNT propelled schrapnel through the right rear door, forcing a piece of the armored door into Herrhausen, pushing him across the back seat into the left door. The force of the explo- sion, which took place 3 feet away from the right rear door of Herrhausen's vehicle, threw the 2.8 ton armored vehicle across the street, approximately 82 feet. The driver was slightly injured. https://www.ojp.gov/pdffiles1/Digitization/153346NCJRS.pdf https://www.ojp.gov/pdffiles1/Digitization/153346NCJRS.pdf
