Narrative:

I was on scheduled break at rest seat 1L jump seat when the first hit of severe clear air turbulence occurred perhaps 3 1/2 hours after takeoff from london's gatwick airport. Besides much vertical movement, there was much sudden and hard horizontal thrashing. This lasted at least 20 mins. Later in-flight more severe turbulence occurred in such manner where I strapped in at jump seat 1R in first class galley. My galley in first class was pretty much secured. I had to hold down a 3 tier service cart from 'flying around' the galley. I had 2 passenger in first class seats, previously 'strapped' in their lounging reclined seats. No injuries to my knowledge.
