Nasa defends rocket to Moon that could shake astronauts to death, Times Online
"Ares is meant to be the rocket that will launch a new era of lunar exploration. Instead it is in danger of crashing into its own launch tower or of shaking its astronauts to death. ... The space agency admits that in certain conditions Ares could blast off into its own launch tower, and that other potential problems include the rocket vibrating so violently that its astronauts could die before they reach orbit."


That "under certain conditions" caveat could be used to create any doomsday scenario one could think of. As in "under certain conditions" the Ares could tip over even before ignition, conditions like say a category 5 hurricane. But NASA isn't stupid enough to roll a launch vehicle out to the pad in a cat 5 storm. Likewise NASA probably isn't stupid enough to attempt a launch under the narrow set of conditions that could cause an Ares I to hit the tower, IE a 13 mph SE wind.
