I'm reading this and few other discussions and it amaze me to see the lack of "30 minutes run dry capability" being perceived as the biggest issue here
The 30 minute dry run to me is possibly the greatest issue, because the question is, to what extent was the crews decision making influenced by the widely promoted claim that the aircraft did have the 30minute capability. Not only in the professional aviation press, but also Sikorskys own promotional material - see below. Unfortunately we will never know.
