Narrative:

Severe turbulence hit unexpectedly while I was in business class galley about 2 hours out of boston as we flew from egll. Captain came on PA and instructed flight attendants to take our jumpseats immediately. I was thrown against the carts on the floor, and following initial turbulence, the aircraft began to dive 10000 ft from FL400 to FL300. I crawled to 2L jumpseat and managed to get into my seat with some difficulty. Plane was shaking and violently shuddering in our rapid descent (less than 2 mins to descend 10000 ft). This was the worst turbulence ever in my 32 yrs. Seatbelt sign was on when we hit turbulence so passenger were in their seats. Many passenger got sick (vomited), 4 flight attendants got hurt. Unfortunately, because turbulence is a phenomena that none of us can prepare for -- other than enforcing the seatbelt sign to protect our passenger, there really isn't anything we can do to protect ourselves as a crew in an event such as this one. The captain instructed us immediately to take a seat, but the instruction came simultaneously with the turbulence. So, in our case, it was too late.

Original NASA ASRS Text

Title: A B777 FLT ATTENDANT RPTED THAT TURB WAS ENCOUNTERED DURING AN OVERWATER FLT FROM EGLL TO BOS, CAUSING INJURIES TO 4 FLT ATTENDANTS.

Narrative: SEVERE TURB HIT UNEXPECTEDLY WHILE I WAS IN BUSINESS CLASS GALLEY ABOUT 2 HRS OUT OF BOSTON AS WE FLEW FROM EGLL. CAPT CAME ON PA AND INSTRUCTED FLT ATTENDANTS TO TAKE OUR JUMPSEATS IMMEDIATELY. I WAS THROWN AGAINST THE CARTS ON THE FLOOR, AND FOLLOWING INITIAL TURB, THE ACFT BEGAN TO DIVE 10000 FT FROM FL400 TO FL300. I CRAWLED TO 2L JUMPSEAT AND MANAGED TO GET INTO MY SEAT WITH SOME DIFFICULTY. PLANE WAS SHAKING AND VIOLENTLY SHUDDERING IN OUR RAPID DSCNT (LESS THAN 2 MINS TO DSND 10000 FT). THIS WAS THE WORST TURB EVER IN MY 32 YRS. SEATBELT SIGN WAS ON WHEN WE HIT TURB SO PAX WERE IN THEIR SEATS. MANY PAX GOT SICK (VOMITED), 4 FLT ATTENDANTS GOT HURT. UNFORTUNATELY, BECAUSE TURB IS A PHENOMENA THAT NONE OF US CAN PREPARE FOR -- OTHER THAN ENFORCING THE SEATBELT SIGN TO PROTECT OUR PAX, THERE REALLY ISN'T ANYTHING WE CAN DO TO PROTECT OURSELVES AS A CREW IN AN EVENT SUCH AS THIS ONE. THE CAPT INSTRUCTED US IMMEDIATELY TO TAKE A SEAT, BUT THE INSTRUCTION CAME SIMULTANEOUSLY WITH THE TURB. SO, IN OUR CASE, IT WAS TOO LATE.
