Another thought...
Based on the description in the article (I haven't had the opportunity to review the NTSB statement) it appears that the real issue is the the craft was not properly designed.
First, the console locked up in the course of flight. Second, there was no notification of stall on the second console so that the pilot could correct the issue before the Predator crashed. Third, upon disconnect from the second console (a designed behavior) the communications gear on the predator stopped responding to subsequent console requests.
While there was certainly human error involved in this accident, it seems to me that the real problem is that this vehicle was designed for combat scenarios, and is unfit to be in the same airspace as civilian flight.
