First of all Training is training and it should not be used as a personal agenda of some trainers to look good themselves.
If one gets employed by an airline one should be more than knowledgeable on the simple aerodynamic and other basic stuff. A lot of it is training bluff and nothing else. A very good standard can only be achieved by good attitude from all.
Training is the the core of the company's safety. Training with the wrong attitude is not only bad in itself but also causes a safety issue. It is just a question of who is on the right side.
