Although this is a rumor network, beware of rumors!
The word on the street is that the pilot is a stand-up guy, and blames no microburst or alien hovercraft downwash. Poor vis, rain, and a tricky rig approach causing surprise water contact is the rumor I heard.
Also, if any ppruner wants to bet me that the NTSB will not invesitgate this accident, I am on, because the NTSB will have their antennae up for any strike-caused laxity. PM me with the amount you want to bet, I will take on all comers!
