That's apparently the theory that two flight attendants are working under, anyway. They are suing the National Weather Service for failing to notify them that there was a pocket of turbulance between Seattle and California.
The lawsuit is being filed now because the statute of limitations runs out on Christmas Day.
This was a terrible accident that resulted in one of the plaintiffs needing several surgeries, but it was an accident nevertheless. I have no doubt that some sympathetic jury will see the poor attendants, note that the government must have millions laying around (they can't have given it all to banks and cash for clunkers, amiright!) and award it to the ladies. Which is reason number 426 why no trial lawyer in his right mind would ever allow me to sit on a jury in a case like this.
