wouldn't one choose to remain over terra firma up to Fehmarn and then have the shortest possible Baltic crossing over to Rødby in Denmark (with ferries departing every 30 minutes below you)?
Maybe that's what he tried to do but
Weather might have been an issue. We had some snow moving in from the west heading eastbound. The last observed heading of the helicopter was a heading of 084 (away from the inbound snow?).
