From a runway point of view-Go minded.
From a weather/type of malfunction point of view-Stop minded.
This is a good reminder that we are NOT guaranteed to stop under these conditions, even if we calculate everything correctly, and even if we perform the abort according to SOP. By saying this, I do not mean to imply that this crew did one thing or another.
The outcome could have been completely different if they had continued the take off with unsafe speed indications.
I'm just a bit curious about the amount of snow on top of the engines at the start of the take off. I did not expect to see that.
BTW,
AFAIK, the evacuation check list is not a memory check list anymore.
