Is it not ferrying aircrafts back to San Diego ? I mean, are these not aircraft in need of servicing or being retired ? A number of them (F6F in front, row after the neatly aligned Avengers) have no engines, the F4F are (older) F4F-3 without folding wings, and it's a motley array of types, including the SNJ in the back.
Could this (if correct) explain the odd decorations ?
