The position of the crash is in the general line of the route, however there is reason to wonder why the aircraft was flying so low.
Looking at the survey photos posted by the Norwegian Air Force, it would appear that the impact occured from the west side of the Kebnekaise ridge, between the north and south peaks, (some?) hundred meters below the ridge. The highest peak being the south peak, 2106 meters AMSL.
One would assume that a route plan for a ferry flight between Evenes and Kiruna would have accounted for a considerable altitude safety margin.
So, the questions stack up:
If there was a technical problem with the aircraft, why was there no distress call? The flight just disappeared off radar.
Some references to SSR information pertaining to the flight has appeared in the press, and it reveals that the aircraft has been flying lower than mimimum clearance altitude a few moments before the crash, passing over the peak of Kuopertjåkka, only a few kilometers away from the impact site.
Autopilot altitude hold inadvertently switched off, and noone watching instruments?
A more subtle technical error that crept up on the crew?
It would be interesting to hear from anyone who has deeper insight into this.
