Narrative:

Cruising at FL350 on J-86 between covia and nepta intxns, deviating slightly north of a major cell, we flew over a small overhang when we hit a violent updraft. The turbulence threw all 3 flight attendants and a number of passenger in the air. The incident lasted about 3 or 4 seconds, and flight conditions returned to smooth air. Our maximum altitude deviation was only about 200 ft. A doctor on the flight examined a few of the most severely hurt passenger who were complaining of back or neck pains. After conferring with the flight attendants, we decided to proceed to our destination and not to divert, but we had the flight met by the paramedics. Supplemental information from acn 282880: several passenger received bumps and bruises from not being strapped into their seats. Seatbelt sign was off, because there was no previous warning of thunderstorm turbulence in the area.
