Hello Commanders!
I'm fairly sure that I've mentioned this topic on more than one occasion. Oh well, once more, with feeling!
We have some ideas for preventing fighter crew death whilst retaining some form of jeopardy, but we haven't got round to implementing them.
Clearly we don't want a situation where crew can always be saved, this would mean that everyone would only ever hire one or two fighter crew. However, we accept that the current situation is too harsh in terms of investment versus risk. Look for more information in a future update.
Thanks for the answer Sandro. Now we know where we stay and this is fine
