You can see exactly how it happened.
She was very spritely during rotation and the speed was trending up to the bricks.
So to stop that, the PF brought the thrust back. The other guy thought WTF and during the chaos, the standard patter was missed. Then they just made some bad decisions (well reactions) during the subsequent events.
EBT is supposed to give good training for this type of event.
I speak from personal experience, but when things are happening, it can take great discipline to prioritise and aviate.
For instance who here has had a slat/flat jam during a go around, received the ecam when you called go round flaps and omitted positive rate, because you were distracted by the ecam? Who then didn’t call gear up because the other guy didn’t call positive rate? I’ll put my hand up.
I trust the crew learnt some great lessons after this event and hope that it’s shared amongst your pilot group.
