I'm withholding judgment until further information is released, such as location of the Mavic relative to the helipad, air ambulance, altitude, etc. etc., but so far it doesn't look good. If the operator is on these forums, it'd be great to hear your side of the story, and to see your flight log! Not expecting it to happen though.
