The "Can Do Trio" represents a scene of two KC-135A (61-0305 and 58-0126) aircraft in refueling formation. The aircraft were based at Grissom AFB, IN back when it was an active USAF base.
I start the pencil study so that I can work out how I want the aircraft and atmosphere to look in my painting. The painting will be a 36" x 24" oil painting.
The sun will be in a little lower, during a very late afternoon position in front of the aircraft, at about a 1 o'clock position and slightly above the aircraft, illuminating their starboard sides. The shadow of the fueling tanker casting a long shadow of it's wing upon the receiver aircraft underneath it.
