Death by Computer
What a time to be alive....... I'm sure some tech will end up taking the fall for this. Ignoring that they were probably under totally unreasonable time constraints and mismanagement.
I bet they won't even be able to produce specification documentation for the project, leave out dreams like comprehensive testing reports.
Sooner or later the IT industry will have its Harrow and Wealdstone rail crash incident and some probably really crap regulation will follow.
