I'm shocked that Ryanair hasn't got a SOP/policy in place to avoid this sort of accident.
Dolley, am curious as to why you think they wouldn't?!
Not saying this is what happened here but people are human and sometimes don't follow the SOP for a host of different reasons. When it comes to open doors a moment's inattention can be catastrophic.
Ryanair, like all airlines, have strict procedures for operations of doors etc. I guess these
might possibly be reviewed after an investigation of this incident but flightcrew and pax falling from open exits have happened before in aviation history. EasyJet had a pilot who fell onto the tarmac in Edinburgh a few years ago.
