i am sure the Raro Air New Zealand B777 incident was well hidden. A select few people in some well connected safety and training department knew but opted to keep it a secret for \x93 gotcha simulator\x92 check sessions.
Likewise the B777 Thrust-Hold/FLCH trap was known for a long time but instructions/examiners kept it to spring surprises. Many checkees got caught but caught everything in time to prevent any great disastrous failure of sim rides. It was only after the Asiana OZ214 disaster in KSFO that they reckoned it was advisable to tell of the trap to all.

Pprune Mind Traps from overwhelming posts

Do not discount the mistaken early flap retraction scenario too easily. Mull on this:

PF commanded gear up on attaining positive rate of climb, fixating on the HUD.
PM mistakenly raise flap lever from 5 to Flap 1 gate. Thrust reduced to Climb Thrust. Landing gear remained deployed. Massive loss of lift misidentified as loss of thrust. If any one pilot just had a dual engine failure scenario on a recent sim ride, brain and muscle memory would jump to loss of thrust in dual engine, prompting them to accomplish the recall memory items which called for both engine fuel control switches to CUTOFF and then RUN, and physically deployed the RAT.

There would be immediate loss of thrust with the engine taking time to recover , if at all, at such low airspeed!
The rest is left for Ppruners’ imagination.😖🥴😬
