[Verse 1]
Vibration table, rattle like a snare drum
Component strapped in, watch the sine sweep hum
Random spectrum shaking loose the coward parts
Thermal vac chamber, cold as the dark's own heart
Minus hundred fifty climbing up to scorching plus
Outgassing checked so the lens don't rust
Shock test next, pyrotechnic snap
Explosive bolt fire, see what cracks the cap
Qualify the part past what it'll ever feel
Margin on margin, that's the only way it's real
[Chorus]
Test as you fly, fly as you test
Bought in blood, learned from the wreckage and the wrecked
Vibe it, bake it, freeze it, shake it down
Static, modal, hot-fire, don't let nothing slide
Test as you fly, fly as you test
Every failure on the ground's a save up in the black
Test as you fly, fly as you test
Prove it on the pad before you never get it back
[Verse 2]
Engine on the stand, chained to the earth like a myth on fire
Hot-fire campaign, count it down, ignite the choir
Every nozzle throat still needs its acceptance run
Before it's trusted with a burn beneath the sun
Test stand shaking, kilonewtons screaming
Turbopumps spinning past what mortals go dreaming
One flight engine, its twin standing witness
Static fire proves the plumbing, not just blueprints
[Verse 3]
Structural bay loading the airframe till it groans
Static loads pushing past the numbers on the drones
Hydraulic rams pulling till the skin panel bends
Find the breaking point before the mission ends
Modal survey shakes it soft, hunts the natural sway
Shaker table chasing frequencies that sing and betray
Every rocket's got a mode where it'll shimmy apart
Map it, damp it, tune it out before the start
[Bridge]
Wet dress rehearsal, load the cryo, run the clock
Practice every heartbeat before the real tick-tock
Hardware in the loop, the software's flying blind
Feed it fake horizons, fool the guidance mind
GNC computer thinks it's really in the black
Simulated stars while the box stays strapped to the rack
Call it a shibboleth — the password of the brave
A rule this old and holy it was bought inside a grave
[Chorus]
Test as you fly, fly as you test
Bought in blood, learned from the wreckage and the wrecked
Vibe it, bake it, freeze it, shake it down
Static, modal, hot-fire, don't let nothing slide
Test as you fly, fly as you test
Every failure on the ground's a save up in the black
Test as you fly, fly as you test
Prove it on the pad before you never get it back
[Outro]
Every crucible we cross before the countdown starts
Melts away the guesswork, tempers all the parts
No shortcuts to the heavens, no faith without the proof
Test it like you mean it — that's the bought-in-blood truth
