The secret of the bumblebee that had scientists scratching their
heads about how it could fly with such tiny wings is that it
flaps them forward AND backward for double the lift.
The design of such a creature is an example of irreducible
complexity. A bumblebee HAD to be able to flap its wings in both
directions from the beginning of its species' existence or it
would not have been able to fly.
This is no small feat. WHY? Because the wing muscle velocity of
movement for a double flap HAS to be able to use energy without
overheating the bumblebee (like the hummingbird, a creature
totally unrelated to a bumblebee). Hence, it has a very special
metabolism, unlike birds (it's far heavier in proportion to its
wings than the hummingbird) and most, if not all, other insects.
This creature is not the product of random chance. The amazing
bumblebee, like ALL the living creatures we see in nature, was
DESIGNED on God's drawing board.

Alpine Swift
Alpine swifts, birds that weigh less than 0.25 pounds (0.11 kg),
are able to fly continuously for more than six months. :o These
birds have been tracked with electronic tags and found to have
been in the air for more than 200 days. It is thought that their
diet of airborne insects and an ability to rest in mid-air are
contributing factors to this ability. Movement tracking devices
for animals were developed in the 1960s, but versions small
enough to be attached to birds weren’t available until the early
2000s.
More about birds' flight:
•A female bar-tailed godwit was once recorded flying
continuously for 7,145 miles (11,500 km) from Alaska to New
Zealand, which is roughly equivalent to a person running 43.5
miles (70 km) per hour for a week.
•Ruby-throated hummingbirds have been found to be able to make a
flight from the Yucatan Peninsula in southeastern Mexico to the
southern US in less than one day.
•The tern is estimated to migrate about 1.5 million miles (2.4
million km) during its average lifespan of 30 years, which is
equivalent to traveling to the moon and back three times.

Though that fuzz makes bees look pretty, that isn't the main

When bees flap their wings, having that fuzz causes a static

[size=14pt]the pollen jumps at the bee! :o Those amazing little
Earthlings were DESIGNED to use Renewable electricity to catch

A butterfly, with its jerky fluttering flight, is NOT a

Why a butterfly flutters by
by David Catchpoole
Have you ever thought that the butterfly, with its jerky
fluttering flight, is a ‘primitive’ and inefficient flyer? After
all, its wings don’t look even remotely aerodynamic, compared to
the beautifully streamlined ‘aerofoil’ wings of birds and
airplanes.
butterfly-flutter
Indeed, just 10 years ago, conventional laws of aerodynamics
could not explain how any of the insects could fly at all,1 let
alone maneuver so masterfully at low speeds—hovering and flying
backwards and sideways, in complete control.
In the last decade, however, researchers have uncovered a
variety of ‘unconventional’ ways that these gossamer aeronauts
use their wings to stay aloft.2 For example, one particular
flapping movement creates a spiraling airflow (vortex) along the
edges of the wings, generating some of the lift which
‘conventional steady-state aerodynamics’ could not account for.3

The fluttering of butterflies is not a random, erratic
wandering, but results from the mastery of a wide array of
aerodynamic mechanisms.
HTML https://soberthinking.createaforum.com/gallery/soberthinking/1-230322175259.gif
LEVs (Leading edge vortices) are the main lift generating
mechanism for insects and is totally different from the steady
state aerodynamics design of aircraft
Now, after filming red admiral butterflies flying in a ‘wind
tunnel’, researchers have been surprised by a whole range of
complicated wing movements which generate more lift than simple
flapping would do:
‘wake capture,
two different types of leading-edge vortex,
active and inactive upstrokes,
in addition to the use of rotational mechanisms and
the Weis-Fogh “clap-and-fling”? mechanism’.4
What is more, the red admirals often used completely different
mechanisms on successive wing strokes!
So, rather than being ‘primitive’, we now understand that
butterflies flutter because they choose each wing stroke from a
customized armory of twists, flaps, claps and flings. In the
words of the researchers, ‘the fluttering of butterflies is not
a random, erratic wandering, but results from the mastery of a
wide array of aerodynamic mechanisms’.4 No wonder butterflies
are so adept at taking off, maneuvering, maintaining steady
flight and landing.
HTML http://dl3.glitter-graphics.net/pub/723/723623pjc70713cu.gif
Aeronautics engineers even desire to copy these mechanisms, e.g.
for robotic spy ‘insects’,5 but there is still a long way to go
before they can match the capabilities of insect flyers.6

HTML http://dl0.creation.com/articles/p004/c00494/butterfly-flutter.jpg
For example, the software design in man-made aircraft requires
many man-years of work and powerful computer chips for its
implementation. In contrast, the flight control center in the
brain of a fly has been estimated at about 3,000 neurons, which
‘gives the insect less computational power than a toaster, :o
yet insects are more agile than aircraft equipped with superfast
digital electronics.’7 So how do insects exercise flight control
over such a wide range of aerobatic abilities?8 One commentator
observed, ‘If engineers ever understand that, there will be a
revolution in aeronautics.’7
HTML http://yoursmiles.org/psmile/pilot/p0503.gif
There is one engineer who understands. He is the One who
originally put these flying marvels together in the first
place—the Lord, the Maker of the heavens and the earth, and the
sea, and all that is in them.

Agelbert NOTE: If you watch closely in the video above, you can
almost see the butterfly creating the double vortices at the
trailing edge of his wings on the down stoke and then being
sucked up by them as it goes into the up stroke. There's an
energy saving secret here! The vortices actually allow the
butterfly to use much less energy to lift its wings for the
upstroke! Amazing!

Please note that the "primitive" insect above called a dragonfly
(found in fossils allegedly over 500 million years old ::) with
the exact same morphology as a "modern" dragonfly) is considered
PRIMITIVE because it has FOUR WINGS. However, science JUST
LEARNED that it can outfly anything on the planet BECAUSE those
four wings are independently articulated for in-phase or
out-of-phase wing pattern flight (22%less power required!). This
is a box canyon logical bag of worms conundrum for evolutionary
true believers. Good!

Dragonfly design tips
by David Catchpoole
Just how can the dragonfly perform its energetically-demanding
aerial acrobatics—flying backwards or forwards, fast, slow or
hovering—and remain airborne for such extended periods?
The answer, in part, is that it has four wings.
While many flying insects use only a single pair of wings (and
very well, too1), dragonflies have [b]‘unusual musculature’ that
allows them to move each of their four wings2
[size=12pt]independently, which is a key factor in their ability
to perform “astonishing acrobatics”.3[/b][/size]
It had been thought that such out-of-phase flapping comes at a
cost, i.e., reducing the amount of lift the insect can generate.
However, bioengineers have built a robotic version of a
dragonfly, attaching sensors at the base of the robot’s wings to
record lift and drag forces, allowing researchers to calculate
aerodynamic efficiency.4,5 And it turns out that in out-of-phase
flapping, the hind wings can extract extra energy from the wake
of air sent by the front wings, reducing aerodynamic power
requirements by up to 22% compared with a single pair of wings.
;D This mechanism, the researchers explained, “is directly
analogous to that exploited by coaxial contra-rotating rotors,
exemplified by helicopters such as the Kamov Ka-50.”4
What’s more, dragonflies have the flexibility to switch between
out-of-phase flapping and in-phase flapping as appropriate. When
taking off, for example, real dragonflies synchronise their wing
beats, thus they are able to lift and accelerate better than if
they used only two wings or four out-of-sync wings.
With this new insight into the aerodynamic efficiency of
out-of-phase flapping, engineers hope to apply it in the next
generation of flapping micro air vehicles.
As one bio-engineer explained, battery life limits how long
micro air vehicles can stay aloft, so “any tips or tricks which
enhance aerodynamic efficiency will be warmly welcomed.”5
It defies reason to suggest that an energy-efficient aerial
acrobat such as the dragonfly was not intentionally, and
intelligently, designed.
HTML https://renewablerevolution.createaforum.com/gallery/renewablerevolution/3-130418202709.png<br
/>
In fact, the researchers involved in this aerodynamic efficiency
study apparently recognized the difficulty their finding
presents to the widely-accepted 🐵 evolutionary scenario,
which posits that four-winged dragonflies arose long before
(i.e., are “more primitive” than) the two-winged Diptera:
--- Quote ---
> “Caution must be applied when interpreting the biological
significance of the above observations. Suggesting an
evolutionary advantage to either two-winged or four-winged forms
is unwise, considering the success and diversity of the true
flies (Diptera), and yet the maintenance of the four-winged form
by dragonflies since the Carboniferous.”4,6
--- End Quote ---

Surely it makes much more sense to say that four-winged
dragonflies and two-winged flies were each designed to do what
they DO do, and what they DO do, they do well! ;D

above scientist that flight is an ability that insects
"evolved", it 's a cool video. There is ZERO evidence of
transitional flight characteristics in insects, period. There
are NO insects with partial wings for millions of years in the
fossil record. But still the RELIGION of the Darwin persists.
The amazing thing about the above scientist's cognitive failings
is that he describes in DETAIL how incredibly specialized fly
sensors and wing anatomy and physiology are DESIGNED ONLY for
flight, not walking, swimming or crawling.
Such Darwinian pretzel reasoning is breathtaking.
