NTSB Narrative Summary Released at Completion of Accident

TWA Flight 374 encountered severe clear air turbulence over Cape Girardeau at FL220 during their initial descent into St. Louis. One flight attendant received a broken clavicle and another flight attendant received bruised ribs as a result of the turbulence. The flight data recorder data showed changes in vertical acceleration between +2.5g's and -0.79g's. A SIGMET for moderate occasional severe turbulence from FL240 to FL350 was issued just after the flight took off from New Orleans, LA. TWA 374 had just been cleared to a lower altitude as it was starting to get 'bumpy' when the severe turbulence was encountered.
