The test flight is delayed due to problems. Kei hears that Gripen is to be scrapped and sneaks into the base. But then, the Xi launch another attack. Gripen needs Kei near her to be able to fly, so he heads up into the sky with her.
If I keep the throttle open, 
then when the Xi passes me...
،إن أبقيت مقبض الدّفع مفتوحًا
...فعندما تمرّ الزّاي من أمامي
Si mantengo el impulso,
cuando el Xi nos pase,
Si mantengo el impulso,
cuando el Xi nos pase,
si je maintiens l’accélération,
même si le Zai passe…
Continuando ad accelerare,
quando lo Xi ci oltrepassa...
Se eu mantiver a potência no máximo,
quando o Zai passar por mim...
