I'd give it up man. I already posted pictures of the plane in question, Aviat Husky, and the fact that you are about 30 inches away from the prop when you get out. I posted that propellers truly disappear in the dark, and at idle there is little localized noise from the prop. Most is from the exhaust.
The pilot was being lazy/careless/stupid and was dropping her at point 'A' at the airport prior to taxiing to point 'B'. He screwed up plain and simple. I know you all hate analogies, but it was similar to dropping a greenhorn on the carrier deck with no training, so he could learn firsthand about jet blast.
