Apparently one of the ferry tanks malfunctioned and the plane ran out of gas. This is another case of a BRS saving lives. Ditching conventionally can be rather dangerous. Anyone who knocks the pilot for not 'saving the plane' is a moron. People before plane. I can only imagine how many armchair pilots are complaining about this. Stop, seriously. If you deploy the BRS within the speed and altitude envelope you will live.
Even more interesting is the recent article by Flying about the BRS.
