And speaking of upsets...wondering if you all remember the chinese 747, lost an engine in cruise...crew didn't notice...autopilot held altitude until airspeed was too slow...bam
Never mind the facts .......
About 1016 Pacific standard time, February 19, 1985, China Airlines Flight 006,
a Boeing 747 SP-09, enroute to Los Angeles, California from Taipei, Taiwan, suffered an inflight upset. The flight from Taipei to about 300 nmi northwest of San Francisco was uneventful and the airplane was flying at about 41,000 feet mean sea level when the No. 4 engine lost power. During the attempt to recover and restore normal power on the No.4 engine, the airplane rolled to the right, nosed over, and entered an uncontrollable descent. The captain was unable to restore the airplane to stable flight until it had descended to
9,500 feet. After the captain stabilized the airplane, he elected to divert to San Francisco International Airport, where a safe landing was made. Although the airplane suffered major structural damage during the upset, descent, and subsequent recovery, only 2 persons among the 274 passengers and crew on board were injured seriously.
