Re #25
I was just quoting the report:
The report states on page 2; the 3rd paragraph - "Due to subsequent traffic inbound EKCH, the pilots on (Sterling Aircraft) were instructed by the approach controller to maintain a high airspeed during descend and approach" (own translation).
I thought it could explain why the crew had their mind set on getting down and out of the way. Of course it does not justify landing without clearance, etc
