I don't see any necessity for viewing the flight deck from the cabin. In fact it would be a disadvantage in these days of heightened security.
IF the official report on the Helios turns out to be what we all suspect happened then better CRM may have been their only saviour.
I've put a scenario to various Cabin Managers over the last few weeks to see what manouvre that they'd expect to "feel the aircraft do" immediately after mask deployment. I've asked what time frame they would expect this to happen in, how long they'd wait for the descent before calling us, what they'd do if nothing was forthcoming etc.
Most of the CMs were right on it, but others hadn't considered this past the usual drills.
Ask your crew what they would do - it's an excellent CRM discussion.
PS. Mike Jenvey - I'd suggest descent in 30 secs not 5 mins!
