> If I was an IC at an airplane manufacturer and a bug I wrote caused an airplane crash - who is legally responsible?

I am not sure it is that complicated, from a legal perspective. It is the company hiring you that would be legally responsible. If you are an external consultant, things may get more complicated, but I am pretty sure that for critical mission software companies wouldn't use external consultants (for this particular reason but also many others)
