The crew were subject to the somatogravic illusion which is human limitation. We have not evolved to assess prolonged acceleration and can easily misinterpret it as pitch up
Somatogravic illusion is often cited by investigators as a contributory cause of many accidents of this nature. That has applied to Cessna 150 go-around accidents as well as jet transports.

If that were true, then one must ask why aircraft carrier pilots who are catapulted at night or in IMC or conduct go-arounds or "bolters," are not crashing in their thousands. The acceleration of after-burner take offs are ten times more powerful than a go-around or take off in an airliner.

No. I believe the problem is simply poor instrument flying skill which needs to be ironed out during simulator training. We see this often during simulator training. Crashes during go-arounds occur in simulators due generally to poor instrument flying skills and inappropriate operation of the automatics. These are not excused as the result of somatogravic illusions. Yet in real aircraft accidents poor instrument flying ability is often covered up in favour of the more politically correct and mysterious sounding `Somatogravic Illusion.`

While there is medical evidence this illusion is a human limitation, it is practically impossible to prove after a crash that it was the primary cause of the accident. That is why the illusion is such a convenient scapegoat in accident reports because it is impossible to prove with any certainty.
