When my engine threw a rod and I landed in a field, at first I prided myself in doing things right, the way I was taught. Then I went through the "what could I have done better?" stages, analyzing what I did, how I did it, the mistakes I made that I had to overcome, etc. I didn't have the NTSB or FAA breathing down my neck with alternatives, but I concocted my own alternatives.

So yeah, it's a normal process of investigation, whether formal via the NTSB or informal, sitting in the airplane after an event, to rehash it and figure out what could have been done better--in case the situation arises again.
