And if one is going to make comparisons: after all that effort were those radical bouncing tactics copied by anyone? Were they ever used again?
The 5th Army Air Force used a similar bouncing bomb technique called "skip bombing" with great success for bombing ships in the Pacific theater. I understand that Australia and Russia used this technique with great success also. The difference is that the skip bomb tactic used conventional bombs released from conventional bombers, mostly B-25s. But B-17s and A-20s were also used by the 5th. The Aussies and Russians used A-20s and other aircraft.
