Section III: Wind Speed and Ballistic Aerodynamics This section addresses the environmental factors that compromised the accuracy of the shots. Atmospheric Conditions: Official weather data confirms southerly wind gusts of 15–30 mph at 12:30 PM. Canyon Funneling: Dealey Plaza’s architecture creates a "canyon effect," causing wind to swirl unpredictably. Aerodynamic Drift: A 160-grain bullet traveling at ~2,100 fps is subject to significant lateral drift in a 20 mph crosswind. For a single shooter to hit two moving targets in these conditions with a cheap bolt-action rifle is statistically improbable. This environment necessitates a coordinated crossfire to ensure the assassination was successful.
Part 3 of 4 Part 2: https://scratch.mit.edu/projects/1307659468 Anatomical Constraint: For a single projectile to align with both victims from the 6th-floor Depository, it would have to transit the President's spinal column. Forensic evidence shows no such spinal destruction, and the "pristine" condition of the recovered bullet (CE 399) is mathematically inconsistent with a high-velocity impact with human vertebrae. This necessitates a separate, direct trajectory for the Governor’s injuries.
