Fire-resistant interiors and stronger seats are just two of the some of the aviation advances that experts say have contributed to more people surviving such accidents. About 200 of the 307 passengers and crew aboard Flight 214 were injured—some seriously—and two died.
Boeing 777s were in development during the late 1980s and early 1990s, and the design took advantage of improvements available at the time, including exit doors that opened more easily, said Airsafe.com Director Todd Curtis, a former safety engineer with Boeing who worked on the 777.
A Boeing spokesman declined to comment, citing international protocol governing aviation accident investigations.
The Asiana aircraft in Saturday's crash, HL7742, was a Boeing 777-200ER, which was introduced in 1997 and is one of the most common variants. Records indicate that Asiana has used HL7742 since 2006.
