Silk Air MI 185
Obviously the majority are convinced this accident was a pilot suicide, along with Egypt Air 990. Don't forget the Royal Maroc ATR 42 in the Morroco area.
It does seem that we have an epidemic of suicidal pilots.
NW 705 was also a pilot induced pitch over into a vertical dive, (The aircraft came apart in the air), The aircraft encountered a pitchup into a nose high attitude, in severe thunderstorm activity and the piot trimmed the stabilizer to a full nose down position. Both vertical gyro's nose down stops indicated severe impact damage from a rapid rotation of the aircraft about its center of gravity.
Read NW Capt. Paul Soderlind's Flight Standard Bulletin FSB 3-65. entitled "Operation in Turbulence" and FSB 8-63 "Jet Turbulence Penetration", to discover how your flight instruments lie to you in turbulence. Paul received 8 awards for his contributations to flight safety. ( He developed the airspeed bug system and the turbulence plot.) Paul died in December 2000.
Until pilots are trained to ignore these erroneous flight instrument indications and rely exclusively on the artificial horizon, in turbulence, we will continue to experience these types of accidents.
In the COPA accident over Tucuti, Panama, when they put the FDR readings thru the computer, the Boeing engineers stated that the aircraft could not have possibly performed these manoevers.!
