Let's see here. Flying at 185 mph, low altitude in dense fog.
I dont know the source for that 185 mph claim,
but that guy interviewed said the bird was more/less
hovering or hunting around just above him in cloud.
[ATC had them waiting, so they were circling]
Thus i cannot realistically imagine the pilot then
Radically gunning the bird up to 185 mph - even
exceeding VNE and crashing just short distance
away from the witnesses location.
I can tell you one thing for certain, - you will know when
an S76/twin PT6 is passing low at top speed in your
near vacinity.... And that is not what the witness described.
