A flying career? I don't think so!
Not strictly on topic, I know, but I am continually amazed with some of the stuff that Cheshire Cat writes. She purports to be seeking a job in an airline eventually, but the immature attitude she displays in this thread, for example, and the abusive tone she takes towards people on this website with whom she disagrees makes me wonder whether she should be let lose in a milk float, let alone a 737!
As many have said before, the aviation world is a small place, and if you slag off enough people whilst using a pen name but with your own name available then some day your CV is likely to be on the desk of somebody who has been at the receiving end of one of these tirades or has at least been offended by reading one of them. Bang goes THAT chance!! Certainly were I in such a position (which I am not), then I would find it hard to look favourably on an application from her given the opinion I have formed since I started reading these fora.
We need all to be aware of the warnings the WWW has outlined so well, not least because of the legal issue but because you, as Wannabes, might regret some of your postings in the future. Check out the thread titled "reply's (spelling!!) to C.V's" (punctuation!) to see how many people who are responsible for sifting CVs have had some input on these fora.
