in regards to the flat wide spacing, these are my first thoughts.
When conducting a head on attack it seemed that the angle of approach was the most difficult thing to align.
Altitude is easy to modify. That said I would think that approaching a grouping as posted would make it easier to line up nose to tail to whichever bomber I could. the wide spread of targets makes any error I make easily transferred to a better aligned target.
Slashing attacks would have easier end targets to pick off rather than approaching a stacked group.
It is my opinion (without further input) that this would not be a good formation to follow.
here are some ideas showing more depth vertically.

I'm open to different options and will follow orders to the best of my ability, just trying to get the best info ahead of time.
