Easier said than done, for sure. I was flying earlier this week to a city in the U.S., and I started getting a little anxious when our plane returned to the jetway, having never made it to the runway. The pilot announced that there was a mechanical problem, and the repair crew was coming to inspect the plane. The pilot would keep us posted on what was transpiring. Shortly after this announcement, he let us know that the engine starter wasn’t working, and everyone had to disembark.
