Pretty good find, Shepp!
A-10s have been stationed here at D-M AFB since I was about 8 or 9. They did some of the prototype evaluations here too.
For airshows they go from brakes-on to airborne in 250'-300' with the gear retracting.
On a carrier for fixed wing, it is always "into the wind" for launch. Hell, look at Doolittle's Raiders:
IIRC, the USS Hornet was about the same size as the USS Guadalcanal.
