Hate to nit-pick (not the posting, incidentally, just the sign itself) ...
but you'd think "they" would have checked for typographical errors before
putting the sign on public display.

First line (not shouting): " ... UNITED STATES ARMY AIR COPRS AT WRIGHT
FIELD ... "

Eighth line: " ... OVER 2,000 AT-6'S WERE IN ASERVICE WITH THE ARMY AIR
COPRS AFTER WWII."

The word is spelled correctly in the 11th line: " ... THE AIRCRAFT WAS A
PRIMARY TRAINER FOR ARMY AIR CORPS AND USAF PILOTS ... "

Last line, main body of text: " .. REAR-MOUNTED 0.30-INCH REAR-MOUNTED
MACHINE GUNE ON A 360-DEGREE SWIVEL."

(And I'll let the use of "ALUMINUM" go through, as being a local
derivative of the correct spelling grin )
