The tarmac and runways on Ford Island have been repaired and there is no evidence of bullet holes from the December 7 attack.

The You Are There sign shows what the Field looked like after the attack.

There are two hangars in which the Pacific Aviation Museum displays are located.
The below photo was taken from inside Hangar 79. A volunteer told me that the holes in the windows are from December 7 while the clear panes are replacements for windows completely shot out.
