I have no doubt of the reality of the plane crashing. I have no doubt of the reality of the tractor mowing. I struggle greatly with those two things happening in conjunction with one another and being photographed as such. I have two issues that my pea size brain can't get around.
First, the odds of the camera being in exactly the correct position to catch the tractor perfectly in the frame and have the plane fly into the pic at exactly the correct time to correspond with the click of the shutter. I don't think it humanly possible to see what's about to happen, and hold the camera steady at a horizontal position and click the shutter when the plane appeared....
Second, the odds of having the shutter speed correctly set, if the camera even had adjustable shutter speed, to catch the plane sharply flying at what had to be an incredible speed while photographing a tractor....
But being from Missouri, I'll let someone show me.
