I don't totally agree with the 10:90 ratio in all photography exercises. I think when you start shooting "still" subjects, then yes, then it's more to do with the person taking the shot than the equipment, since you have time on your hands to "create" a good shot.

However when it comes to shooting fast moving subjects I think it's got a little more to do with the equipment you shoot with since you don't have the time to compose a shot - if you have to take the shot - you have to. Yes of course I'm not saying you simply just focus and press the shutter, but I do think that you are not able to compose that "artistic" shot like you can with "still" subjects. You just don't have the time to adjust aperture, shutter, bringing in another object into the frame to give it that "artistic" effect. Now here is where a good camera comes in handy. If a camera can take decent shots, lets say on auto, and it's a decent lens you can get "proffesional" looking shots all with the equipment doing almost all of the work for you.

I have a SLR camera and I'll be quite honest, even though I get sometimes - "now what do you have an SLR camera for" , a lot of times I shoot at AUTO mode - only because the AUTO mode of this camera takes really good pictures. Although I love shooting manual (this is where a person starts doing more of the composing of what the photo will look like afterwards) it's just to much if you start shooting planes in an area where you have a lot of colour variation like dark spots etc. You set the camera for the dark area and lets say you miss the shot you have to readjust for the lighter side of the runway for instance. We as humans just don't always have that speed to do that adjustment properly and a camera with a good auto function (leaving it up to the equipment) makes life a lot easier sometimes.

"Still" subjects I prefer going manual since I like to create shots which has another object in the foreground and I like to play with lightning and depth, but 50% of the time if I shoot fast moving planes I use auto.
