The emergency services have to safely get to the incident, possibly using the extra entrances for that purpose. Aircraft full of passengers landing at the same time as emergency vehicles trying to get to an incident of potentially unknown severity seems like a recipe for disaster. Aviation is a shining example of how thought about risk, learning from failures/mistakes and evolving standard operating procedures can almost completely de-risk an inherently risky environment. I came across this article after the incident in SFO earlier in the week: http://en.wikipedia.org/wiki/Boeing_777 http://en.wikipedia.org/wiki/Boeing_777 No flight related deaths since it began service in 1995 - I've been thinking about that all week. That is some inspirational engineering.
