I think jumping up and down is a rather healthy activity!
However, jumping up and down here on PPrune is not going to get ANY action or even a reaction from your guy's management, not positive anyway. Rather go public! Newspapers and civilian blogs are the way to go. If it's as bad for you individuals as I'm lead to believe, then it can't be safe really, which means the travelling public who pay for carriage (dearly) are
entitled to know what's going on at Link. Or not? Is it right and correct for it to be kept secret from them too? Just asking.......
