A couple of flight attendants were saying that an Emergency Procedures instructor had said that the legislation had gone through and they were most concerned that on the 737/800, in the event of a ditching, one of the flight attendants would have to stop the passengers using the rear doors to escape and by doing so, was sacrificing her life! If the legislation was to go through, I wonder if CASA would have to obtain proof from the airlines that they could evacuate their aircraft within ninety seconds with a reduced crew? I was under the impression that the relevant legislation hadn't gone through too but these two girls were adamant that it had. I guess the pilots would be the last to know anyway.
