[SystemSafety] 737 tail strike caused by typo on a tablet

This news article is likely to be of interest to the list members. A jumbo's tail struck the runway on take-off, and root cause was found to be an incorrect take-off weight entered in the thrust parameter calculator. The fact the calculator is an app running on an iPad may or may not be important to the story, but it does give it that everyday appeal.

The calculation is double checked using pen and paper, and so two dissimilar faults were necessary to invoke the failure vector. Is there anything more that can reasonably be done to avoid this safety issue?
