> In SFO you'll end up in the bay or hit the terminal depending on the orientation.

The bay is survivable and I don't think you can hit the terminal. You could possibly hit the freeway though. That said, two of the runways at SFO are 1.5 km longer than the one in Korea.

> In Toronto you'll crash into a highway.

That runway is 1.5 kilometers longer than the one in Korea and it's another kilometer to the highway that sits uphill.

In Toronto, the 427 is ~100m from the edge of 24R.

[Aloisius]

Landings/takeoffs from 23/24R/24L are in the westerly direction (away from 427) due to prevailing winds.

But in an emergency is it impossible for aircraft to land in the opposite direction? That's what happened at Muan; the concrete structure was only present if the plane landed against the normal approach.

[Aloisius]

Impossible? No, but the fact that planes generally don't approach from that direction and there are other, longer runways to land means substantially reduce the risk of an already extremely rare event.
