Peter Anderson, in his Ineffable Con 5 session, was asked about the name of the boat in the pile of items that the procession climbs in the Season 2 intro. He didn't know off the top of his head. But he did follow that up with: "Speaking of which, did anybody look at the bus? What was on the bus?"
He didn't really elaborate on the bus, other than it "was a special Good Omens bus."
Let's assume for the purposes of this post that he's talking about a bus in the intro, which was the current topic of conversation. (Rather than the actual, in-service bus that was wrapped to promote the series.) I am pretty sure this is the bus in question:
There's an ad on the side, which is interesting. Wings for Victory was a fundraising effort in 1943.
And there's also what looks like a route identifier on the front:
I think this says GO2 (as the route number): Soho, Green Park, Victoria; Soho Square. That's a fairly reasonable bus route; the actual 38 bus takes a similar one.
In the X-Ray, Peter Anderson also brings up where the bus is going. Very briefly. So clearly it means something to him.
There is one more thing I found, because of course there is. Amazon did a behind the scenes tour of the Season 2 set as a prize for a promotional contest. There was a bus involved:
Interestingly, there was also a TikTok including the bus which shows a different set of stops for the route.
What does it mean? I have no idea. Ours* is not to reason why; ours is to deliver packages. Of research. What do you think?
