A friend of mine worked at Hardy's until recently as C & T as well as flying the C441 and Metro. I believe it was his job that was advertised. It doesn't surprise me that there are problems since his leaving as he was constantly been called on to fill in on short notice. Even if you are an aviation tragic as he is that would get tiring.
As for Directair, the training school and engineering shop were all run as separate entities so the closing of one does not mean the closing of all although that might depend on how they are closed. If it was through a creditors application for bankruptcy then that might close the lot but not otherwise. I have my suspicions as to how its problems arose but I am not going to say further on an open forum.
