Most dangerous airports in the US
9. Boston Logan Airport
Logan International Airport, with its harrowing history of near misses between aircraft on busy runways, became in 2010 the nation's first airport to introduce an elaborate new system of lights and radar designed to prevent such collisions and close calls. The new system, which cost $3.6 million, is expected to be installed at 23 airports nationwide in the next few years, federal aviation and transportation officials said.
