Turns out the reports have been greatly exaggerated, and the initial "back
of the envelope" calculations did not take into account things such as
turbulance at the trailing edge of the wings, which tends to assist lift
in this case.

I went to a lecture ten years or so ago by a team investigating bee
flight (I suspect bumble bees are used as an example because they seem
a particularly lumbering and unaerodynamic case). If I remember
correctly they had got far enough with the theory that they had a
workable model of actual bumble bee flight - the only flaw was that
the bee would have to eat the equivalent of a Mars Bar every minute to
stay in the air.

(remove the Xs to reply)
My memory is that an eminent person used the aerodynamic knowledge of
his day to calculate the glide characteristics of a bumble bee &
concluded that it couldn't glide. This became couldn't fly. I
understand the modern day computations take into account the complex
wing movements & the lift created by the vortices generated.
As an Aeronautical Engineering student many many moons ago, I attended a
lecture on flying that was illustrated by some fascinating slow-motion
footage of various insects in flight, which had been taken long before
then. The lecturer commented with some irritation on that UL and said
that the then-current methods of analyzing flight could only cope with
fixed wings. As he pointed out, the wings of the bumblebee on the screen
were clearly not fixed---they were flipping over in a fascinating
figure-of-eight motion within each stroke so the bee was getting at
least some lift from them on the upstroke as well as the downstroke.
So although "scientists" (including Aero Engineers, presumably) were
well aware at the time of _how_ bumblebees flew, from viewing such
films, it wasn't yet possible to _analyze_ that motion.

when we were just beginning to think we understood aerodynamic
principles, as applied to fixed-wing aircraft, but scientists recognized
their limitations in applying the principles to the birds and insects and

Brings to mind some of the gaffs I've seen on maps in recent years.
Apparently a lot of map publishers are contracting out 'somewhere'
and not bothering to check their accuracy with pre-existing local
maps or surveys.
Five or six years ago I picked up a map of the city I live in, to replace
the tattered 20-old version I'd had forever. I was surprised to find a
two-mile long lake within blocks of my house, where for as long as I've
lived here there has been a grassy park (and no lake; not even a pond).
A little reearch revealed that there had /never/ been a lake on that spot,
though there had been a hill that was leveled when the park was put in
40 or so years ago.
Of course that just covers human history. It's possible that there may
have been a lake there in geological history, I suppose...
Has anyone else heard the story that Rand-McNally left out one of the
50 states in the annual edition of one of their road atlases? I've not
looked into that one, though I've heard it a couple of times, always
with a different state identified as missing (most recently, Oklahoma).

A coworker of a friend of mine was once sent out to do a live shot for
a news show. He was talking to someone at the station who was guiding
him via a city map. When instructed to turn left on X street, he
replied that there was no such street at the location indicated.
Presumably it was another trap.
Years ago one of the local traffic reporting outfits suspected their
information was being stolen by a competitor. So one morning they
reported that a certain street was closed due to a fire. Sure enough,
not long after the competitor reported the same thing. Unfortunately I
can't remember if it was the street name that was made up, or just the
fact of its being closed.
I remember the same sting being run in Dayton OH when I was stationed
there, circa 1966. I don't think any of the stations there were using
helicopters at the time, but a couple of them had Cessnas for the
traffic-reporting role and another was merely pretending to. Station
A's "Eye In The Sky" announced an imaginary accident blocking a
street, then announced a few minutes later that Station B had poached
it.
Of course, nobody listening to Station B heard the revelation, so its
impact was a bit limited.

A few years ago, my local fishwrapper had a story about the new "official" map of
Indiana, published by some state agency. They'd looked at it, and
found several towns they'd never heard of, in the two counties that
are their circulation area. They went to the places in question, and
they people there hadn't ever heard of them either. In one case, they
found an old guy who said "That used to be the name of the Standard
station" or something like that.

The inclusion of a lake of significant size where no lake has never

me as something other than a copyright trap. On a state level most

engines and controls are nearly disabled by an electromagnetic pulse and

Well, one, this thread began with the mention of something stated in a
movie, didn't it, and two, a movie has at least as much to do with
aerodynamics and reality as the often repeated urban legend that science
agrees that bees require supernatural help to fly.
Also a friend of mine was killed by a bee. I realize that bees are
required for the pollination of crops and that if you make them out of
terrycloth they're cute but I never liked them much. They're mindless
hive creatures. Their poetry is monotonous and their dance is a tropism.
I prefer cats.

I do too, but they're not much use at crop pollination. Try persuading a
cat to flit from fruit tree to fruit tree, spreading pollen.

As for feral hawgs, wild boar and bears, you're simply "S.O.O.L." (Shit out
of luck!) hunting with a pack of cats, most likely to desert you to get runt
over or et as the case (or the critter may be).
On second thought, there are few more viscous creatures than feral cats
which seem to adapt as quickly to the wild as do strayed swine. While pigs
change dramatically in appearance in the second generation, cats may
continue to look the same, but their predatory instincts make the survivors
efficient killing machines. A male feral will kill the kittens fathered by
another male as quickly as a lion will get rid of the offspring of a
previous consort of a lioness which he fancies.
Of course, they don't pull down many deer (but play havoc among nesting
quail).

There were cats in North America when the white men arrived, but no
bees. They do call them European honeybees. Of course the apple tree
is also an import, and I believe, citrus trees as well. Maybe the
native cats pollinated the native fruit trees. My cat climbs fruit
