Why a Blackburn Blackburn question became a Swordfish lesson

What if the US Navy chose the Blackburn Blackburn instead of a monoplane torpedo bomber?

A Swordfish-style biplane could suit night operations, but the later correction makes the Blackburn Blackburn a much stranger US Navy choice.

The initial response treats the biplane form as a response to an operating concept rather than simple backwardness. Night flying increases pilot workload and makes deck operations harder, so a forgiving, repairable aircraft has value that daytime performance comparisons can miss. The audience later clarifies that the hypothetical aircraft was the Blackburn Blackburn rather than the Swordfish. The reply concedes that putting the Blackburn Blackburn into US Navy service would create a very strange fleet instead of claiming that the two aircraft were interchangeable.
