Narrative:

We waited on runway, delaying takeoff, for approximately 2 hours due to unsatisfactory WX conditions. A storm was pounding the airport with a strong driving rain. The captain stated in a PA that due to extremely wet runway and tailwinds, we would wait for better conditions. We changed runways and the storm appeared to blow over us. We took off and turned left (west) and seemed to head directly into the storm. We never settled into the air and had a stable feeling. The plane felt weightless and I floated in my harness in the jump seat. This continued with the plane jolting and free-floating, then we pitched forward, nose down, momentarily. I was told later by the crew we hit a windshear at 10000 ft. Callback conversation with reporter revealed the following information: the reporter stated that the plane seemed to take a nose-dive at one point and frightened the cabin crew and the passenger, some of whom became hysterical. She said that the captain never once gave a PA to explain to the passenger or crew what was going on. He later explained that he was afraid of waking people up. After their encounter with the windshear, other flts decided to wait out the storm. Supplemental information from acn 457959: we go to the other end of the runway to take off into the wind -- evidently there was a shift in wind direction. Now, we take off I believe to the north and make a right turn directly into the storm! Aircraft drops severely 4 to 5 times. We headed right into the storm. We always make a right turn and head out towards the ocean - but the storm was right there. Why did the captain take off - that's the question - especially after waiting all that tine and he even saying he wouldn't take off in bad WX over the PA.

Title: CABIN ATTENDANT RPT, B777, NRT-ZZZ, ON TKOF, PLANE HIT WINDSHEAR AT 10000 FT AND TOOK A SUDDEN NOSE DIVE. PLTS GAINED CTL. EMOTIONAL TRAUMA TO PAX, CABIN ATTENDANTS.

Narrative: WE WAITED ON RWY, DELAYING TKOF, FOR APPROX 2 HRS DUE TO UNSATISFACTORY WX CONDITIONS. A STORM WAS POUNDING THE ARPT WITH A STRONG DRIVING RAIN. THE CAPT STATED IN A PA THAT DUE TO EXTREMELY WET RWY AND TAILWINDS, WE WOULD WAIT FOR BETTER CONDITIONS. WE CHANGED RWYS AND THE STORM APPEARED TO BLOW OVER US. WE TOOK OFF AND TURNED L (W) AND SEEMED TO HEAD DIRECTLY INTO THE STORM. WE NEVER SETTLED INTO THE AIR AND HAD A STABLE FEELING. THE PLANE FELT WEIGHTLESS AND I FLOATED IN MY HARNESS IN THE JUMP SEAT. THIS CONTINUED WITH THE PLANE JOLTING AND FREE-FLOATING, THEN WE PITCHED FORWARD, NOSE DOWN, MOMENTARILY. I WAS TOLD LATER BY THE CREW WE HIT A WINDSHEAR AT 10000 FT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THAT THE PLANE SEEMED TO TAKE A NOSE-DIVE AT ONE POINT AND FRIGHTENED THE CABIN CREW AND THE PAX, SOME OF WHOM BECAME HYSTERICAL. SHE SAID THAT THE CAPT NEVER ONCE GAVE A PA TO EXPLAIN TO THE PAX OR CREW WHAT WAS GOING ON. HE LATER EXPLAINED THAT HE WAS AFRAID OF WAKING PEOPLE UP. AFTER THEIR ENCOUNTER WITH THE WINDSHEAR, OTHER FLTS DECIDED TO WAIT OUT THE STORM. SUPPLEMENTAL INFO FROM ACN 457959: WE GO TO THE OTHER END OF THE RWY TO TAKE OFF INTO THE WIND -- EVIDENTLY THERE WAS A SHIFT IN WIND DIRECTION. NOW, WE TAKE OFF I BELIEVE TO THE N AND MAKE A R TURN DIRECTLY INTO THE STORM! ACFT DROPS SEVERELY 4 TO 5 TIMES. WE HEADED RIGHT INTO THE STORM. WE ALWAYS MAKE A R TURN AND HEAD OUT TOWARDS THE OCEAN - BUT THE STORM WAS RIGHT THERE. WHY DID THE CAPT TAKE OFF - THAT'S THE QUESTION - ESPECIALLY AFTER WAITING ALL THAT TINE AND HE EVEN SAYING HE WOULDN'T TAKE OFF IN BAD WX OVER THE PA.
