I was woken up by this running of engine of a plane or jet plane in the middle of the night - September 28, 2009 at 03:16 AM. It ran for a while and I finally sat up and checked out the window and saw a plane at the terminal. What is this plane doing at this time of the night?

Here is the reply from the Island Airport:

We have received your comment and email concerning an engine run up during after hours at the Toronto City Centre Airport on September 28, 2009 at 0316 hours. Our Flight Tracking and Noise System tracked a Q400 aircraft in front of Hanger 6 conducting an Engine Run Up between 0337 hours to 0350 hours. We apologize for any inconvenience. We ask that engine run ups are conducted in our restricted area, during normal airport operating hours. We will be contacting the airline for further investigation.

We thank you for your comment, and it has been entered into our monthly reports.

So Porter did an engine run up in the middle of the night. Can someone explain to me why they have to do it at this time and at the terminal? If I do not complain about it, will the Island Airport find out by themselves and if they will act on it at all.

So we need to keep doing our job - keep complaining.

A very worried Mom
