"I think a great example of this happened a couple of months ago on the job for me. As the head mechanic covering a busy weekend, I found out on short notice that a passenger plane that had just landed needed a very quick turnaround on a mechanical issue, with a scheduled flight being just four hours from the time I was notified. My first step was to confirm with the captain of the crew that no other aircraft was available, and he confirmed there were not any available. Knowing that the issue generally took a few hours with two men on the job, I immediately called in for another mechanic to join me. Knowing it was going to take about an hour for help to show up, I began doing as much prep work as I could to ensure we completed the necessary maintenance. I hustled to prepare our tools for the job and pulled all of the relevant manuals. When help arrived, the actual hands-on work took just over an hour, and the plane was ready well ahead of schedule to take off to its next destination."
