Avalon Airport: minutes from being a flight from hell

Was aboard the flight from Avalon airport. I have never experienced anything like this before. Now on another flight and I feel so stressed.

I was sitting in the middle of the plane and remember seeing the pilot get out from the cockpit and hurriedly tried to get what seemed to be a staff member wearing the yellow hi-vis off the plane. Then some passengers at the front started crying. Some people will have a video. Thankful to be alive today.
