Narrative

15 MINS AFTER TKOF OUT OF BOS; I NOTICED THAT WE STILL WEREN'T CLBING. I WENT TO THE COCKPIT TO ASK IF ANYTHING WAS WRONG; AS I WAS PURSER ON THIS FLT. THE PLTS WERE TRYING TO MANUALLY PRESSURIZE THE CABIN; SINCE THE AUTOPRESSURIZATION WAS BROKEN. MANUALS WERE OUT; AND THEY WERE ON THE RADIO TO DISPATCH AND OUR MAIN MAINT FACILITY. THE CAPT SAID THAT IT LOOKED LIKE IT COULD BE FIXED; BUT NOT TO USE CARTS OR SERVE FOOD YET. I RETURNED TO MY FIRST CLASS CABIN DUTIES. WITHIN MINS; WE STARTED TO CLB; BUT THEN MY HEAD STARTED TO HURT AND I WAS DIZZY. I COULD FEEL US QUICKLY DSNDING AGAIN. I RAN TO THE COCKPIT AND ALL 3 PLTS HAD THEIR OXYGEN MASKS ON. THE CAPT SAID THAT WE WOULD NOT DECOMPRESS; THAT THE PROB COULD NOT BE FIXED; AND WE WOULD BE TURNING AROUND AND GOING TO JFK TO GET ANOTHER ACFT. WE DID THAT; AND THERE WERE NO FURTHER INCIDENTS. JUST A NOTE: THE THIRD OFFICER (PLT #3) WAS INSTRUCTED TO MAKE A PA 1 IN BEFORE LNDG AT JFK BY THE CAPT ABOUT THE RESCUE VEHICLES ON THE RWY. PLT #3'S PA WAS VERY UNPROFESSIONAL AND BY TRYING TO JOKE ABOUT A SERIOUS SIT; HE UPSET MANY PAX. THEY LET US KNOW HOW HE HAD MADE A BAD SIT WORSE BY JOKING AND NOT BEING PROFESSIONAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE COCKPIT CREW TRIED THEIR BEST TO MANUALLY PRESSURIZE THE PLANE WHEN THEY CLBED ABOVE 10000 FT; BUT IMMEDIATELY BEGAN A FAIRLY RAPID DSCNT AFTER EVERYONE; INCLUDING THEMSELVES; WERE GETTING SYMPTOMS OF ALT SICKNESS. THE CAPT CAME ON THE PA TO MAKE AN ANNOUNCEMENT TO THE PAX DESCRIBING THE NATURE OF THE PROB (AUTOPRESSURIZATION) AND TO REASSURE THEM OF THE SAFETY OF THE PLANE. HE EXPLAINED THEY COULD EITHER GO BACK TO BOSTON AND CANCEL; OR GO TO JFK AND CHANGE AIRPLANES WITH ONE COMING IN FROM LAX. IT WAS ON LNDG AT JFK THAT THE THIRD PLT MADE AN ANNOUNCEMENT ON TOUCHDOWN THAT UPSET AND VISIBLY SHOOK UP THE PAX. HE SAID; 'IF YOU SEE ALL THE RED LIGHTS OUT THERE (IE; FIRE TRUCKS AND AMBULANCES) WHEN WE LAND; DON'T WORRY; WE'RE NOT GOING TO CRASH.' HE DIDN'T ELABORATE THAT THIS WAS NORMAL OPERATING PROC. AS THE PAX GOT OFF THE PLANE AT JFK; MANY WERE CRYING; AND SOME EVEN YELLED AT THE OFFENDING PLT. AFTER A MEGA DELAY IN JFK; THEY GOT UNDER WAY AND HAD A NORMAL FLT. WITH THE LULL IN SVCS GOING ACROSS THE ATLANTIC; THE RPTR (THE PURSER) TALKED WITH THE PLT; WHO MADE THE ANNOUNCEMENT; ABOUT THE HORRIBLE EFFECT IT MADE ON THE PEOPLE. HE WAS NEW AT THE POS; AND WAS SUFFICIENTLY MORTIFIED ABOUT THE BAD EFFECT HIS ANNOUNCEMENT MADE THAT HE VOWED TO NEVER DO THAT AGAIN; AND THAT HE LEARNED FROM HIS MISTAKE. UPON LNDG IN PARIS; THE PAX PROFUSELY THANKED THE CREW FOR THEIR SAFE ARR.
