The helicopter pilot said you most likely wouldn't be able to see it from the road, as he could barely make it out from the air.
You mean that you aren't going to go photograph it, so that certain people on this thread will believe it? How uncharitable of you. It can't possibly be true(sarc.)
He was talking about the car.
Here is what he said about the tire tracks...again this is from YOUR post. Why would the pilot (your source as you claim) said "obviously probably seeing the skid marks leading off the side of the road"
DUFFY: I`m not sure that we can actually take full credit for spotting the car. At the same time that we arrived searching the area, a state trooper also pulled up, obviously probably seeing the skid marks leading off the side of the road.
GRACE: So there were skid marks?
DUFFY: There weren`t any black marks on the asphalt, but from the air it was visible, tire tracks leaving the road surface going into the swampy area, yes, ma`am.
