I’m sure we’ve all made mistakes, and I’m sure a great amount of us have grown from them. As we are human beings, we can only do so much, mistakes happen.
For example, I was a newly promoted Specialist operating Tower at KLAX. I accidentally created a conflict between two aircraft on final when there didn’t need to be one. This was entirely caused by me as I forgot about them while handling a situation on the Ground frequency. A plan is important to have and what I was missing.
In that circumstance where I was super busy, I panicked. Splitting frequencies would’ve helped me in that case.
No matter how many times you fail, you must learn from it and keep trying!
