Just a thought but CHIRP also has reports from cabin crew, ATC and engineers.
A forum discussing flight safety by airline pilots without input from other aviation professionals is unlikely to be able to analyise all aspects of a given situation in most instances.
Just airline pilots might also lead to a great deal of egotistical "willy-waving" of how much time on time, years in the industry etc. a particular individual has - let alone inter-company rivalries.
I'm probably just jealous because, as an employed biz-jet pilot, I wouldn't be allowed to play (nor the countless ex-airline pilots in GA)- or maybe there are no GA pilots who could add to a debate on flight safety
