Even though I enjoy doing "ground based" work and have built many 2 camera rigs, my passion is single camera aerial hyper-stereo. My wife and I are both pilots and own a Cessna 182 and when we go on photo excursions she's in the left seat as "pilot in command" and I'm shooting out the right side of the airplane. Typically my images are several hundred feet apart and because it's so hard to "frame" shots in the air I take many images and pick the best pair. All my work is aligned and cropped in "Stereo Photo Maker".
