Re: It's not my fault, the Software made me do it!
I disagree.
If you as a developer provide a critical system which has two menu items next to each other - you have to expect someone to mis-click at some point. Everyone's done it with their email program at some point, and sent something to junk mail, or deleted it or whatever.
Only this is a safety critical system. With email it doesn't matter so much, though the menus could be better designed.
In this case a distressing and potentially panic-inducing false alarm was issued. Which is bad enough.
In the worst case scenario, there's a real incoming nuclear attack and someone hits test - and no alert gets issued.
By these early accounts, it's a shit design.
