Nick,
They had indeed rotated. Now, whether it was because they had reached Vr, or it was a last ditch effort to get above the Citation, I donīt know. Iīm sure we will soon, if we just let the investigation teams do their job.
But an ACARS "off" report was received in Copenhagen from the aircraft datalink system.
Itīs a datalink report, automatically sent when the nose strut of the aircraft extends on rotation, and the ground shift mechanism senses that the nose is in the air.
