Built a C-UAS ballistic trajectory simulator with:

**Physics Model:**
- **Gravity** - Standard 9.81 m/s²
- **Aerodynamic Drag** - Cd × ½ρAv² force opposing velocity
- **Magnus Effect** - Spin-induced lateral force (Cm coefficient, cross product of spin axis & velocity)
- **Wind/Crosswind (Xg)** - Adjustable speed & direction, affects relative velocity
- **Coriolis Effect** - Optional Earth rotation compensation (45° latitude)

**Features:**
- Presets for .50 BMG, 20mm Vulcan, 30mm AHEAD, 40mm Bofors
- Customizable muzzle velocity, mass, caliber, drag coefficient
- Elevation & azimuth aiming
- Wind speed/direction with visual indicator
- Spin rate control for Magnus effect
- Target drone with position, altitude, velocity
- Auto lead-angle calculation
- Trajectory comparison (with/without Magnus, with/without wind)
- Real-time flight data: TOF, max range/height, impact velocity, drift values, energy

**Next Ideas:**
1. **Burst Fire Mode** - Fire multiple rounds with dispersion pattern to simulate AA gun engagement zones
2. **Mach-dependent Drag** - Add transonic/supersonic drag coefficient curves for more accurate ballistics
