[Verse 1] Ignition sequence, vehicle's alive, skin vibrating through the air Dynamic pressure climbing fast, aerodynamics everywhere Drag is axial — opposes thrust — it scales with velocity squared Lift is lateral, angle of attack, every degree declared Reynolds numbers in the boundary layer, flow is turbulent and raw Nose cone geometry determines how the shock wave forms its claw Fins are passive stabilisers, weathervane the stack upright Centre of pressure trailing centre of mass — that's what keeps the flight [Chorus] Max-Q is the moment — dynamic pressure peaks Structural loading maximum, the airframe speaks Drag times density times velocity squared, divide by two Throttle back and hold the angle — that's what you do Gravity turn, gravity turn — pitch over, let physics steer Trajectory bends orbital, the atmosphere is clear Max-Q, gravity turn, ascent trajectory Memorise the sequence — that's the key [Verse 2] Ninety seconds off the pad, watch the dynamic pressure swell Q equals half rho vee squared — that formula you know well Engineers throttle engines down approaching maximum-Q Structural margins paper-thin, the vehicle flexes through Wind shear slices horizontal — gust loads twist the stack Day-of-launch trajectory shaping compensates and gives it back Angle of attack near zero through the thickest atmosphere Bending moments minimised until the thinner layers clear [Chorus] Max-Q is the moment — dynamic pressure peaks Structural loading maximum, the airframe speaks Drag times density times velocity squared, divide by two Throttle back and hold the angle — that's what you do Gravity turn, gravity turn — pitch over, let physics steer Trajectory bends orbital, the atmosphere is clear Max-Q, gravity turn, ascent trajectory Memorise the sequence — that's the key [Bridge] Now flip the script — reentry physics, ablative heat shield taking blows Plasma envelope blackout window — comms go dark, nobody knows Stagnation point sees temperatures that melt titanium clean Ballistic entry steeper, higher decel, brutal and obscene Lifting entry — shallow glide, spreading heat across the time Lift over drag ratio gives the corridor its line Skip reentry bounces off the upper atmosphere like stone Thermal soak and pressure loads — you earn your way back home [Verse 3] Gravity turn initiates with a pitch kick off the rail Velocity vector leads the nose — you follow without fail Prograde pointing all the way, the atmosphere dictates Orbital insertion where the perigee negotiates Ascent trajectory optimised for payload mass and fuel Lofted arc trades downrange distance — every gram's a duel Depressed trajectory's faster but the heating bill's severe Net delta-vee is everything — the algebra is clear
