" This the article on that bloke's new system for natural language to program code? Sounds interesting. Why would a misplaced minus sign result in flipping an aircraft like this? I don't think the natural language system is going to stop errors like this. People will still need to tell it to be wary of the equator and check for such things. Anyway it's unlikely that people will use it in such areas for a long while (until it's proven reliable and correct). My penny's worth, Chris Campbell
