Get the Flick: Air Traffic Safety vs. Capacity

Get the Flick: Air Traffic Safety vs. Capacity: "Let me use our theoretical runway capacity of 60 planes per hour once again. Imagine if we could schedule it perfectly. Imagine if we had 60 airplanes per hour scheduled for every hour of the day. Then imagine if there was just one tiny glitch -- weather, a flat tire or an airport vehicle mistakenly wanders onto the runway. An arrival has to go around and make another attempt to land. Where do you find the extra slot for that aircraft ? Every slot is taken for every minute of the day. But the airplane must land or it will run out of fuel just like Avianca 052. That makes the decision easy for air traffic controllers. An arrival takes priority over a departure. They will use a departure slot for the arrival. Now the departures will be delayed for the rest of the day -- or in this theoretical case -- for eternity."

Money vs Safety
And this is different from Space Shuttle Challenger how?
