You lose points for this,
<quote>if there were no airline pilots you would not have any pilots to train in the first place.</quote>
There are hundreds of thousands of pilots in the world, and hardly any of them fly for airlines. Since there are still hundreds of thousands of pilots who don't apparently know how to fly from birth, we must teach those who wish to learn, maybe for fun. The logic behind saying "every airline pilot must have been taught once" does not hold for the inverse "every instructor must teach airline pilots". Our club has about 150 pilots, none of whom fly for any airline. Are you saying these people don't exist?
Since you list your occupation as pilot, but are in the Instructors' corner, I thought you honestly didn't know this. No offence.
Safe flying
