At least two or three times the pilot (?) says "fermez le bouche" which is "shut your mouth" or "shut up."
"Quoi?" is "What?"
"Arret" is "stop"
"feu" is "fire"
"perdu" is "lost"
"escalier" is "staircase"
regardless of whether they asked for a ladder or staircase, clearly they didn't wan't to be in the cockpit anymore.
"D'accord" is "okay"
"sh*t" is "sh*t"
"mal" is "bad" or "sick"
The fireman may have messed up the test, and there may not have been enough water pressure, but there was a fire and he was trying to do what he'd chosen to do as a career.
