Cpt has just going through med check (it was his first flight after). FO is ex cabin crew, graduated Chelavia private flight school - yes, 140hr at Tecnam P2002 and P2006 and then 672 on type.
And last rumor from "sources who listened to CVR" - it was Cpt who take control and doesn't listen to FO which disagreed with his course of action and suggested right things, unfortunately in vain.
