The challenge can be described as your average English listening test. From listening the recording multiple times, here are some parts that I can understand.

The most important parts are "air canada 248", "133 65 airport", "touching down on 02", and "could take off 30".

I gave these facts into GPT and it gave me this explanation.

To confirm, we can check on Edmonton Airport's runway numbers. We can see that it indeed has the number "02" and "30", just like what the recording says.
