"Faint heat traces"
Swedish media reporting that a Royal Norwegian Air Force F-16 had picked up faint heat traces at three different points in the presumed area. A Danish SAR helicopter also reports having picked up a "faint ELT signal" from the same area. Last positive contact was at 13:43 UTC, so in daylight and in an area notorious for 'mountain waves'. Norway's Armed Forces Minister earlier in the day dropped a bollock by confirming "all on board dead", only having to retract this statement later.
