Glen, James:
during and shortly after WW-II there were aero industry experiments with
"laminar flow wings". One of the schemes involved lots of tiny holes in the
skin (of the forward portion and/or the "cusp", I'm thinking). Instead of
blowing air out of the holes, they sucked it in. I wonder if Noble wasn't
doing the same thing? (I sure would be more comfortable sucking some air
out from under that thing, rather than increasing the pressure underneath.)
As I recall, the aero industry proved their theory to be helpful, but they
had a maintenance nightmare trying to keep the little holes unplugged.

Richard Noble's Jet car had hundreds of small holes in the belly pan of the
car just for this reason.
