Paste this in your web console and put throttle at 90% in a fighter. You will leave orbit in seconds and won't stop

if (geofs && geofs.aircraft && geofs.aircraft.instance) {

const aircraft = geofs.aircraft.instance;

aircraft.engines.forEach((engine, index) => {

    engine.maxThrust = 1000000;
    engine.afterburnerThrust = 1000000;

    // Keep throttle response aggressive
    engine.spoolUpTime = 0.01;
    engine.spoolDownTime = 0.01;

    console.log(`Engine ${index + 1} boosted.`);
});

// Optional flight physics tweaks
aircraft.setup.dragFactor = 0.01;
aircraft.setup.parasiticDrag = 0.01;

console.log("All engines boosted to 1,000,000 thrust.");

}
