What this does show is the importance of having the appropriate cleared and graded area at the runway edges. Some big international airports I've been to have uncovered pits, trenches and god knows what in this area - all traps for both off piste aircraft or evacuating passengers.
Whether to "skew" or not as you stop for an engine fire with an X-wind is becoming more of a briefing item for us, especially on the more long bodied -300, and most especially at airports with less benign runway shoulders....At some places putting in a minor turn as you stop is going to put those going down slides at 5L or 5R into a storm drain, or worse...personally I'd be grateful to just get stopped and doubt I'd have the capacity to do much else..

As for the comments about 15 seconds between "stopping" and the "mayday"...
very much
