I have not seen the movie, but I think I saw what you're talking about on a preview. I would think that the safeties involved in the control system for a crane would make it highly unlikely to happen. There is no absolute assurance, only probabilities or likelihoods. You just hope that you have enough failsafes in the system so if one part of the system fails, the others will take over, or shut the whole thing down properly.
