Does anyone have a good link or source for how the formation lights were used on B-17's and B-24's and B-29's during WW2 Formation bombing? I am curious as to what they meant and how the formations were constructed and maintained in flight. What aides other than formation lights? Were those lights effective in daylight? I have often seen references to a formation ship. This seems to be an aircraft painted rather differently and used for the flight to form up on initially but I have never read a good description of how the nuts and bolts of formation flying was achieved.
