If it had gone onto 401, with 16 lanes of traffic in rush hour...
It is a natural feature and I agree that it certainly prevents an aircraft going on to Highway 401.
If you
look at a diagram of CYYZ, you will see that the extended centreline of 24L does not intersect the 401 freeway for over 1km from the end of the runway/ravine. To 'go on to' the 401 would have required a 90-degree slew. IOW, media hype.
This ravine in nearly 80 feet deep and I thnk that it is ridiculous that such a hazard still exists at the end of such a major international airport runway.
Why have Transport Canada taken no steps in over 25 years to remove this hazard?
Think you've answered it yourself - cost effectiveness - 1 (well 2 now) in 25+ years does not constitute a significant hazard to the beancounters
I would think that since 24L is the
new runway, some crush zone at the end could have been included. Ah yes, there's that cost thing again.
