Here is my experience with wake turbulence.............. KPDX - KDEN; UAL 733: As most of us know, anytime flying in & out of DEN
turbulence is to be expected. On this particular flight (while listening to channel 9) we where experiencing the normal bumps flying over the Colorado Rockies, I heard ATC tell our flight deck crew that we where following a heavy 767, followed by the standard "caution wake turbulence". I didn't think anything of it because you hear this all the time. Not more than 30 seconds after that, in a blink of an eye, the aircraft violently knife edge to the right and back level then repeated one more time. Everything that wasn't secured went flying thru the cabin, luckily the FA
's had already taken their seats, if they would have been up it could have been real ugly. After things settled down the Captain came over the speaker and said a larger aircraft (767 had descended informs of us causing the turbulence). Ever since then wake turbulence has paranoid the hell out of me.
