Whenever there is a helicopter accident, it will be discussed here. The vast majority of the pilots here are seasoned professionals and not only want and need to learn (as we all do) from these accidents but some may well have known the pilot.
When you start training, you will be told about the pitfalls and how to avoid them, you will hear some scary stories and some sad stories. There are some pretty unedifying statistics like the average life expectancy of a PPL who flies into cloud is measured in seconds. If you can manage it, a trip to the AAIB in Farnborough is well worth it; very sobering.
