there is the basic traduction. The NOSA is the Navigateur Officier Système d'Armes (WEASO in the english terms)
Pilot : c'est parti (here we go)
NOSA : ca va ? mad ? mad mad ? (are you okay ? mad ? mad mad ?)
PIlot : oui oui oui (yes yes yes!)
NOSA : on est en piqué là (we're in a deep dive now!)
Pil : ui ui (yes yes)
NOSA : sors sors sors ! sors du piqué sors sors (pull up pull up get out of the dive pull up)
(once climbing again)
Pilot : ca va ! (it's okay)
NOSA : oh putain (oh **** it)
Pilot : ca va (it's okay!)
PIlot : j'ai l'avion (I have controls)
NOSA : c'est bon c normal ? (Is everything Okay?)
PIlot : j'ai l'avion (I got it)
What happened here is a G-LOC for G-Loss Of Consciousness
Google "G-LOC" for more information.
The pilot entered in an hard turn (about 4 g's) and get out. The NOSA called him MAD which is his nickname for wake him up.
When he wook up, a few seconds was necessary for him to understand the situation, and the NOSA took the commands and pull back to exit the aircraft of this situation.
During the dive you can see the sound wall is broken (mach meter on the upper left side below the indicated air speed) and the minimal height reached is about 180 feets above ground level.
A situation which could have been very worst without the intervention of the NOSA.
