Narrative:
Approximately 40 mins after takeoff, the plane began to shake violently. I've been a flight attendant for 15 yrs and I've experienced turbulence. However, this seemed to be much more. It was not side-to-side. It felt more of a front/back motion. I was barely able to get into my jump seat. Luckily, since we had just taken off, most passenger had their seatbelts fastened. The vibrating and front/back motion lasted for about 30 mins. We then were able to check on the passenger for about 5 mins. The captain announced flight attendants prepare for immediate landing. The shaking started about 5 mins after that. It was worse than the prior. The captain landed the plane in sro. No evacuate/evacuation was necessary. I truly believe the aircraft had a problem, such as the aircraft elevators. Both pilots agreed that the aircraft must have a mechanical problem.

Title: 40 MINS AFTER TKOF IN A B757, ACFT SHOOK VIOLENTLY FOR 30 MINS. FLC DIVERTED TO ALTERNATE WITHOUT INCIDENT.
Narrative: APPROX 40 MINS AFTER TKOF, THE PLANE BEGAN TO SHAKE VIOLENTLY. I'VE BEEN A FLT ATTENDANT FOR 15 YRS AND I'VE EXPERIENCED TURB. HOWEVER, THIS SEEMED TO BE MUCH MORE. IT WAS NOT SIDE-TO-SIDE. IT FELT MORE OF A FRONT/BACK MOTION. I WAS BARELY ABLE TO GET INTO MY JUMP SEAT. LUCKILY, SINCE WE HAD JUST TAKEN OFF, MOST PAX HAD THEIR SEATBELTS FASTENED. THE VIBRATING AND FRONT/BACK MOTION LASTED FOR ABOUT 30 MINS. WE THEN WERE ABLE TO CHK ON THE PAX FOR ABOUT 5 MINS. THE CAPT ANNOUNCED FLT ATTENDANTS PREPARE FOR IMMEDIATE LNDG. THE SHAKING STARTED ABOUT 5 MINS AFTER THAT. IT WAS WORSE THAN THE PRIOR. THE CAPT LANDED THE PLANE IN SRO. NO EVAC WAS NECESSARY. I TRULY BELIEVE THE ACFT HAD A PROB, SUCH AS THE ACFT ELEVATORS. BOTH PLTS AGREED THAT THE ACFT MUST HAVE A MECHANICAL PROB.
