If this guy was wearing a Captain's uniform (someone posted that there is TV evidence of this) it will have been noticed by other crew members on lay-over. How come no-one, including his fellow Captains never said anything to him ? Often, the greater majority and some times the entire BA crew would go off to some school or orphanage for this type of, heartfelt, off duty activity.Wood's activity, in going off to some school dressed as a Captain, would not have gone without notice to his fellow crew members.
This assumes he wore the bogus uniform around the hotel and other crew members and didn't simply change when he got to where he was going. I'm sure wearing a captains uniform around the hotel would have been a big red flag to others so why make such an elementary mistake given the lengths he'd already gone to to conceal his crimes? He might as well have worn a gold tracksuit and a Jim'll Fix It badge in the lobby.
