Very clearly stipulated , in Ryanair, & I think pretty much all companies, no matter what happens in Cabin, flightdeck crew ABSOLUTELY prohibited from leaving the cockpit to intervene (in some respects a bit anal I know, & sometimes you really WOULD like to come back to deck the b@stards, but I think we all know / understand where this prohibition came from.)
So, if this report isn't just BS, one more DEC vacancy in FR methinks.
