Are my eyes failing me or is the person helping her to disrobe a female? At least twice she appears to sit on the lap of the person who is occupying the right seat to get help with undoing a piece of clothing. Both times the helper appears to be a female from the makeup and the earrings. Wonder if the flight had a female copilot or if another cabin crew member was up there, depriving the paying customers of their service.
Perhaps the investigation will disclose a malfunction in the system controlling oxygen levels in the cockpit, and they were suffering from hypoxia which made them act silly.
