Daily Herald (Chicago, Oct. 31) -- As authorities investigate why a GE engine failed and led to fire aboard an American Airlines jet Friday, records show federal authorities had asked the manufacturer to fix problems with that type of engine previously. Human error is the single-largest factor in airplane problems, University of Illinois Urbana-Champaign aviation security expert and professor Sheldon Howard Jacobson said. "Mechanical is second-most frequent. Weather is third. Sabotage and terrorism is fourth. Given the volume of flights per day, and small number of reports of problems, one can see why air travel is as safe as it is," Jacobson said.
