It starts at about 1:53. If you freeze the footage there or at 1:54, you are seeing a couple of seconds before she blew up. Freeze it at 1:55, and you can see two things... 1) The explosion starting, and 2) a hand off to the right of the screen pointing up into the sky at the plane which attacked her.
As Tracy has noted, that plane was very high up. So high up that it is not in the image. All you see is the hand pointing up to where it is "up there," out of the frame. You also do not see any other planes anywhere around in the background.
The attacking plane was a level bomber...a Kate torpedo bomber, but with bombs instead of torpedoes. The level bombers had lined up one behind the other, and spaced 200 meters apart. Then they all made their runs from South to North and bow to stern. Each group of about 5 planes had an assigned ship for a target as they came in single file up Battleship Row.
All this comes from the 1952 account of Mitsuo Fuchida, who led the attack. That account is here:
So, if you want to do this diorama, and show just the Arizona just as she was hit, you need a single Kate flying over the ship pointing from bow to stern. To put it in scale, as Tracys wrote, you would have to mount it ridiculously high over the model. If you lowered it down to something more reasonable for display, most people probably would not object.
