Yeah, I had several disagreements with the aerial article and the Kenyon Labs article.
Shutter speed listed would only be required for 200mm on an APSC sensor flying low to the ground. I have plenty of dead sharp images from a 40mp 645d down as low as 1/200sec when using a 35mm lens and flying low. It depends a lot on focal length which was completely ignored.
And only mentioning about choosing a gyro based on the camera weight? Huh? It depends a lot on how much stabilization you actually need to which is based largely on:
Video or stills? Low light (sunrise) or mid day? Lens focal length? Resolution?
I constantly change the shutter speed, aperture, and ISO as conditions change to get the best possible image. Would never dream of just using shutter priority. Of course I work a lot of pre dawn, dawn, up to about 1.5hrs after sunrise shooting into the sun away from the sun and 90degrees to the sun. Would never dream of working much later than 2hrs after sunrise, aerial landscapes gain so much from the shadows.
I don't even know why you would want that long of a lens. You loose a lot less sharpness from haze and dust in the air by shooting wider form a lower perspective. People say but yeah then the wing gets in the picture or the strut... Rent a bigger plane. Cessna 210 is perfect (6 seater with no strut) and find a more experience pilot to control the wing when you are shooting.
And why shoot through a window open or closed? Take the door off and add a wind deflector. Pull the front seat out and slide the back seat forward. Sit on the seat or sit on the floor etc. Just wear a harness, you wont fall out anyways it is near impossible.
I have a KS 4x4 and find it an indispensable tool. It is even very useful handheld on the ground (I don't have image stabilization).
