I got the same impression reading the preliminary report.
From the report, emphasis mine:
Between liftoff and 1000 ft above ground level (AGL), the pitch trim position moved between 4.9 and 5.9 units in response to manual electric trim inputs. At 1000 ft AGL, the pitch trim position was at 5.6 units.
I'd like to know exactly what terms were used in this exchange:
At 05:41:46, the Captain asked the First-Officer if the trim is functional. The First-Officer has replied that the trim was not working and asked if he could try it manually. The Captain told him to try. At 05:41:54, the First-Officer replied that it is not working.
I still can't figure out why nobody pulled back the power with continuous overspeed warnings on both sides and obviously too much thrust for attempted level flight.
