Well, I think it probably gets into some sifting jobs when you have an aircraft compacted the way you do. You don't know where to look for things. Therefore they will have to be examining it almost like archeology in this case. James McKenna, the image of something as big as a Learjet flying halfway across America by itself is a pretty striking image. It happens simply because the airplane is equipped to fly on its own.
Most modern jets are.
And if for some reason the pilots become incapacitated, there's nothing to stop that airplane from continuing its flight until it runs out of fuel. Given the way auto pilot works the original course was for Texas. It ended up in the northern plains. The plane most likely flew itself there. Flying a course on auto pilot is a sequential activity.
