For some reason, possibly runway maintenance or an incident on 23R, flights are currently landing on 23L, leading to this situation: OJ rolled long and waited in the loop for JH, which used the turning circle after landing, and they then backtracked to the terminals.
I guess this had been going on for a time, as I had noticed various aircraft holding a bit earlier, quite unusual for Manchester at this time of night.
Thanks to the RB user showing ground movements there.
