absolutely, it is there. get down low enough over flat seas and you can feel
'something', akin to being on a down bed, held over a hard bed.

Yabbut - Helicopters are _different_. (And the Navy, of course has to
be different, too, so Navy Helicopters are _very_ different)
In the case of a Fixed-Wing Aircraft, proximity to the ground kills
off the wingtip vortices, In Helicopters (Hmm... If Airplanes are
Fixed Wing Aircraft, I guess that means Helicopters are Broken Wing
Aircraft), you're either piling up the rotor wash faster than it can
run away, or the Earth is vastry increasing its repulsion of the noisy
beast in a last-ditch effort to keep it from marring the ground.

Different, as in similar but not quite the same, or Different as in NQR?

That's the current theory.

or the Earth is vastry increasing its repulsion of the noisy
beast in a last-ditch effort to keep it from marring the ground.

That's the only current competing theory.
Having seen more than my share of between-the-wars European bomber designs, I
KNOW UGLY. Hell, if the earth repelled ugly designs, Brequet would hold all of
the endurance flight records.

Helicopters do not marr the ground with their visual presence - they are simply
generators for localized disruptions of the normal laws of physics.

Choppers are known as rotary wing a/c, and ordinary a/c are known as fixed
wing a/c.

Some of us know them helicopters and airplanes, respectively.
