Quiz Question: Economics of Airport Runway Overruns

By Paul Kedrosky · Wednesday, December 12, 2007 ·
Quiz question for readers. First, however, a quote:
"In the past 25 years, at least one aircraft a month overran a runway somewhere in the world - one aircraft a month," said Wendy Tadros, chair of the [Transport Canada Safety Board]. "As the trend continues, aircraft are bound to overrun Canadian runways."
Assuming there are 28,537 commercial flights per day in the U.S. (source), and making appropriate assumptions to come up with the number of commercial flights per day worldwide, how much should Canadians be willing to spend to builder longer runways?
