AfricanSkies: What noteworthy sermon are you trying to make about forum participants who may "speculate" about a theory, or about a probable cause, of an airplane accident?
Isn't it self evident that you or anyone else in this forum is permitted to engage one's brain to sort out people's opinions?
Obviously, many participants are not "professional pilots." In fact, many interested forum participants may be clueless about aviation altogether; yet they may easily masquerade on Pprune as such, because it's free, because it's easy to sign up, and because it doesn't require an aviation employe identity check.
So, relax and be at least entertained by these global discussions.
