I dont really agree with saying that if there is an emergency then pax can just open the do and hay presto 125+ passenger evacuated with no problem, in that case why should we be there if they are so capable of getting out on their own?
Also, some 737 slides are not automatic, like those on the old -200, u have to locate and pull manual inflation, do u think a passenger would know to look under the flap marked "manual infaltion handle" what if the slide dosnt inflate properly? and also a valid point, are they aware of the checking for hazards outside etc...
Anyone know if there is any CAA regulations on this?
