On the Helios, as I understand it.The cabin crew had only just managed to enter the flight deck minutes before the engines ran down due to lack of fuel.
I imagine, if they had entered the flight deck much earlier, the outcome could well have been different.
With regards to the oxygen being switched off. On all the 73's I fly, The oxy tank is located in the forward hold and can't be turned on or off by the crew.
Pull out the mask and put it on, the rest is automatic.
The switch that killed them all was the presurisation, being in manual and not automatic.
I have also flown a number of types with locked doors. None have had more than one code option. The doors remain locked untill all electrical power is removed, and they don't open on depresurisation.
