I was personally interested in recounting how the accident came to occur, not the fact that the pilots forgot about the flaps and the plane blew up, but why they forgot the flaps. And what was the process, because forgetting the flaps was the straw that broke the camel's back in a series of tremendous violations of regulations. I was interested in portraying what isn't apparent about the accident, not just the final link (the pilot). Because all the links that came before were conveniently hidden because they compromised the establishment, the business.
