There are some big questions here. Did they "cut the corner" whilst lining up? If so they must have been going a fair speed to throw debris into the right engine! If they moved off the centre line to the extent that the nose gear was "scratched" ....... That's a 22.5m deviation if they were on the centreline at the start.
Anybody have any FACTS regarding this one?
They knew they'd done it because they told ATC. If it was in the initial part of the take off, why didn't they stop? Would you want to bring the gear up having gone off piste
I don't know much about the culture in Finnair but this incident does not inspire confidence.
