Since rotor failure during normal flight within the operating limitations of the aircraft is a rare occurance and 3 seconds isn't enough time to do anything usefull, there is no surprise there. -- Jim Pennino Remove .spam.sux to reply.

And seismic activity, especially in the Western US, has been heavily instrumented and monitored for decades now. No method to date to do predictions based on history. -- Jim Pennino Remove .spam.sux to reply. |
