Why hasn't there been a case of an airliner breaking apart and crashing due to turbulence in the past 40-50 years?

Most of the breakups involved clear air turbulence as well, the type that still can't be detected today. Examples like: Boeing 707 (BOAC Flight 911) - which crashed near Mt Fuji BAC One-Eleven ...

Can a modern airliner handle turbulence forces of +5/-3G?

In the BOAC Flight 911 accident the 707 likely experienced around positive 5G and negative 2-3G. The wings of the 707 were only about as 50% as flexible as the wings of airliners today. How would a ...
