Ben, Widmore, Miles and Lapidus and the crash
I guess Ben did "desire" to get that plane down and Jacob made Widmore do it.
I believe Ben has the ability to alter circumstances by desiring a certain outcome and due to some form of control he has over Jacob, it just so "happened" that a surgeon dropped from the sky along with a bunch of people Jacob had on " a list".
At first it seemed obvious Ben would have faked the crash, but the method and " smell" of the whole operation is very WidmorŽish (Had Lapidus been hired after calling in "the fake" ? )
320 passengers x10.000 $ each= 3.2 million $ Miles would probably know about the fake and its cost as well.
Happiness is not an ideal of reason, but of imagination.
