Narrative:

I was sitting in my jump seat adjacent to the mid galley approximately 10 mins after takeoff. We had just completed the 180 degree turn out over the pacific and were heading back eastbound. All of a sudden, I noticed that the mid galley power went out as well as all the reading lights in the coach cabin. The cockpit told the purser we were turning around and going back to lax because we had lost a generator. Because of the significant decrease in airflow, I was having difficulty breathing, but as soon as I quit moving about the aircraft, I felt significantly better. Upon descent, the flight attendant across from me felt extraordinarily noticeable vibrations under her feet. Upon investigation, mechanics found a crack in the covering of the #1, l-hand engine.
