Which is why they needed two pilots to switch off flying formation, as stated.

Two pilots was obviously better than a single pilot when flying
formations, however that does not mean the RAF would have gone down that
route for daylight ops. Bomber Command pilots were already flying 8 hour
sorties, some as long as 12 hours (in the Hampden the pilot could not
move from the seat - no access to the rest of the aircraft). It is more
than likely that Bomber Command would have retained the single pilot
(with the increased workload) faced with the need to modify aircraft and
a pilot shortage.

It is not correct to assume that since the USAAF had two pilot aircraft
and used two pilots on daylight ops, that you _need_ two pilots when
flying similar ops. Also, it is not correct to assume that since the
USAAF used large, tight combat boxes, that you _need_ to use such
tactics. There's even a suggestion that daylight ops may not be the only
answer when you take cloud cover into account.
