PS Do we actually know for sure it was the FO who landed?
Not from any of my sources, no. Might just be a rumour.
Buuuuuut, we have some successful landings from FOs when manure hit the AC (like the aforementioned LHR 777) and we have some very unsuccessful landings from when Capt took over late in the landing sequence (Southwest noseplant comes to mind).
Hindsight is always the best thing, right?
