Physics of Totality Dilation:
Lunar shadow velocity across the curved Earth at 20.2° N latitude is ~2,250 km/h. By flying eastward at Mach 2.05 (2,170 km/h) along the path of totality, relative shadow overtaking speed drops to just 80 km/h. Inside a 250 km diameter umbral cone:

T = D_umbra / (V_shadow - V_jet) = 250 / 80 = 3.12 hrs (~74m tracked path).
