There were two fatal airplane accidents over the weekend: Asiana Airlines Flight 214's crash landing in San Francisco killed two passengers, while the fiery crash of an air taxi in Alaska claimed the lives of all 10 people on board. The twin tragedies have raised questions about the safety of air travel, but experts say that passengers can rest assured that flying is safer now than it has ever been.
One reason is that aircraft — especially large commercial airliners like Asiana's Boeing 777 — are structurally more sound than ever. Another is that improved cockpit technology has made collisions less likely. Large crashes are still big news, but that is partly because they're so infrequent. Here is a look at the record, by the numbers:
Asiana Flight 214 passengers who were killed when the jet, coming down too slowly, hit a sea wall and crashed onto the runway. The victims, Ye Mengyuan and Wang Linjia, were both 16-year-old students from China's eastern Zhejiang province, part of a group heading for summer camp.
Passengers and crew members who survived the crash. "It may have been worse if that fuselage had been designed with practices that were common 20 or 30 years prior," said former Boeing safety engineer Todd Curtis. There also might have been more fatalities, he said, if the accident had happened in a developing country without an advanced trauma center nearby.
