I would try some solvents on the spray paint, see if there's anything that will dissolve them to reveal whatever's underneath. The fact that the bomber went right over the headset etc suggests he too no time to prep, so the original decals may well be there still.

What solvents do I mean, you ask?

I'd start with naphtha, progress to goo-gone, goofoff, etc. On a nice day when I can go outside and work in the open air, I'd try acetone, xylol.... something's bound to work. You may find the original paint down there and not even too bad.
