I'm pretty sure he was head of the cleaning team, so he needed to get the plane cleaned and restocked ready for the next flight. I'm sure they mentioned it in one of their much older vlogs, although I'm not going back to find it!
Saying that, it was creepy who said he was 'head' of the cleaning team, in reality he probably wasn't!
He used to film the planes and things whilst he was on shift ?
I think he omitted the ‘dick’ in front of head of the cleaning team.
