This is like saying the reason YOU are dumb is because YOU had bad teachers when you were at school...give us a break...
Locust Hunter,
My quote does not infer that YOU are dumb because of bad teachers, it infers that there maybe a deficiency in the training process, or that the experience of the pilots does not lend itself to good airmanship.
From the Macquarie Dictionary - Dumb: stupid; dull witted.
It appears you might be the dumb one.
