>  Hi Mark,

Hi Keith...

>  Are you talking lighter-than-air, or ultralight as well?

Either way is a problem in some of the weather conditions under
which these sightings have occurred.

A balloon with a hundred or more foot lighter than air wing would
be incredibly hard to maintain in any sort of wind because the
slightest pitch up or down or lateral would drastically increase
the surface area available for the wind to affect. Because these
transitions would be very rapid and probably chaotic, I would
tend to doubt that even fly by wire systems would do well.

An ultralight has similar problems. All it takes is a brief look
at an ultralight coming in for a landing to realize that even
with a mere 20 foot wingspan, the ultralight can have serious
control problems in even mild crosswinds. But many of the
observations of large boomerang type objects have been of things
100 feet or more across, with the objects at altitudes which fall
readily into the stero vision range. Obviously those would be
even more unstable.

Hang gliders ride the winds. There is some ability for a hang
glider to remain stable in specific areas of updraft (near
ridges, for instance), but in a strong 40-50 mph wind I suspect
that a hang glider would be hard pressed to do anything but go
with the flow.

The trade-off is weight/power vs. surface area. Now these
aircraft, if they existed, would have a wing area easily as large
as a 747, but at that weight, using conventional power plants to
produce the energy needed to stay in the air at the reported
altitudes, they would make a sound like thunder. Once we get that
far, we have to then say, well, they don't need that much power
because they're lighter. But as they get lighter, the wind
becomes more effective against their surface area and they become
less stable in winds.

Well, I'm not going to try to knock at people who have
demonstrated their knowledge and their ability in various fields,
except to say that a true judgement of the practicality of this
sort of aircraft in the flight regimes required to account for
sightings such as the extensive Hudson Valley reports would fall
to aeronautical engineers. I'm not one of those, but I do have a
keen amateur interest, and the "giant flying wing" sets off my BS
detector whenever its proposed as an alternative for sightings
like those in the Hudson Valley.
