A few casual thoughts on this painting.
First, I thought those white things were clouds but after looking closely at the one by the ship dock, I now think some of those are from the result of bombs exploding/burning targets on the ground. The one over the water in front of the ship's bow looks like it splashed in the water. So....I'm speculating the painting depicts an actual photo of a bomb run. There is a low aircraft over the runway that maybe pulling out of the run.
Second.....I did some casual looking (Googling) on the name Rusie. If the OP wanted to research further, here are some initial leads to work with to see if they go anywhere.
Seems there are indeed Rusie's in Indiana. One being baseball Hall of Famer Amos Rusie.
https://en.wikipedia.org/wiki/Amos_Rusie I also came across this United Way Youtube of an older lady in Indiana named Ruth Rusie. Could her or Amos be connected to the painting?
