Hello What next,
thanks for the link... I agree with your thinking & doubt the prop was 'feathered' in the conventional sense of the word. I reckon it stopped with a high blade angle and only momentarily struck the ground due to the dynamics of the final moments inverted on the ground before coming to a rest as we saw in the photos. This whole prop business is a 'red herring' in the big scheme of things - as the AAIU have told us so in so many words... ;-)
