Pilot makes first NVG Antarctic landing

From CNN - A U.S. Air Force pilot has landed a plane in Antarctica in
the dark for the first time using night-vision goggles, a feat that
could lead to more supply flights to scientific bases in the frozen
continent during its dark winter months, officials said Friday.

The C-17 Globemaster cargo airplane landed in a driving snowstorm on the
10-kilometer (six mile) ice runway at the U.S. Antarctic research center
at McMurdo Station, after months of practice runs by pilots using the
goggles.

The Air Force plane took off from Christchurch, New Zealand, and flew
nearly six hours before landing Thursday night. It returned to
Christchurch early Friday.

Air Force Lt. Col. Jim McGann said the airplane's own lights --
reflecting off of traffic cones -- allowed it to land without electrical
runway lights that are too hard to maintain in the frozen environment.

McGann told New Zealand's national radio that the breakthrough flight
could mean year-round supply flights for U.S. and New Zealand science
bases on the ice.

Traditionally, the onset of the southern hemisphere winter in Antarctica
ends flights to the frozen continent for six months as the sun sinks
below the horizon.

"At the moment, we make that last trip in February and then don't come
back until August," McGann said. "If we can go in and out a couple of
times a month, we can go and get people out or drop more people off."

The head of the New Zealand government's Antarctic research body, Lou
Sanson, told The Associated Press that the flight was a technological
achievement that would allow the U.S. Air Force to operate virtually
around-the-clock on the harshest continent on Earth.

"I think the most significant advantage is medical evacuation," he said.

At least three major medical evacuations have been carried out from
Antarctic bases in recent years, including an emergency flight for a
U.S. doctor at the South Pole who had developed breast cancer.

Sanson said the night-flight breakthrough also opens new opportunities
for research.

"If we look ahead 10 years, it may offer important new opportunities for
winter science, be it the study of sea life growth or emperor penguins
in winter -- it gives the ability to put scientists into there for a
short time rather than the whole winter," he said

You would think that they could just use retro reflectors, rather than
go the NVG route.

Good point - actually CNNs "traffic cones" - dumbed down to witches hats
in the minds of it's natural audience, were in fact retro reflective cones.

"Major Corey Simmons, the pilot, was ecstatic that he and his crew were
the first people in aviation history to land on the Antarctic continent
at night.

"We just did the first NVG (Night Vision) landing on Pegasus using retro
reflective cones that we have been testing for about 18 months or so,"
said Simmons."

"It was actually pretty challenging & with some heavy snow, so when we
first extended the lights out into the environment it's probably like
you've seen snow at night with your car and your high beams on and it's
come at yah .. well that was coming at us, except at 180 miles an hour,"
says Pilot Lieutenant-Colonel Jim McGann.

 But the four hour flight in the end was smooth and the 20 pilots
onboard were all given a chance to see how the winter flights will work.

"The  goggles were fantastic, the outline and runway were perfectly
clear we could see it from three miles, rolled right in picture perfect
landing," says McGann.

I had thought they were talking about standard runway marker cones.
I'm guessing that it was retro reflective "tape" on  runway markers if
they still needed NVG at three miles.  Corner cube type retro
reflectors in a reflector package are much brighter and are visible to
the naked eye at 3 miles with typical lighting.  But I suppose the NVG
would also give them the benefit of a horizon.  

I'm sure they have their reasons for doing it the way that they have.

Can NVG's see through a driving snow storm?

Good question. And with the aircraft's landing lights on, the amount of
reflected light from the snow-flakes would normally overwhelm the goggles. I
know from personal experience that NVGs aren't that great when using them in
heavy rain and active illumination.

Which was pretty much what I was thinking.

High intensity IR LED's in the landing lights would do the job quite well
without having to worry about the reflected active illumination from the
main landing lights, in conjunction with IR reflectors (as used on the back
of most military vehicles in night time full tactical situations) would
finish the job, Hell I have been doing some experiments with IR stuff for
the last couple of months, and it would seem pretty trivial (and I can get
my pissy little civilian grade high intensity IR's to project for at least
100 meters with a decent reflector) so for the guys in the military who have
been working with this stuff for decades it should be a relative walk in the
(dark)park :-)

MILspec goes to -40. I had a freezer to test electronics
that went lower, wires shatter, metal brittles. You'll need
to extend your specs to -120F.

your also assuming that the de-icing on the AC is turned off ??

:-), you can email the A-S base and ask them,
maybe you have  good idea!

I only asked because the de-icing could also be used to keep the IR's warm
enough to work in hostile conditions :-)
Not having anything to do with MIL spec stuff in decades (and only having
discussions with a mate who has recently retired from the US military, who's
professional purview was all things IR and thermo [and only things of a
distinctly NON military nature])
I might just put this too him as he now works for a military contractor, you
never know it might just work :-)

Some people in the A-S station keep blogs, that I
occasionally read, very interesting stuff, and they
have email addresses. IIRC metal embittlement is
a problem, so they need use the right alloys and
so forth.

  Antarctica gets very little snow which makes me wonder what CNN's
definition of blizzard would be.

Three snowflakes.

Have a look at any of the cameras on the ice during a storm.
Most of the snow comes in horizontally

  That's windblown ice. Antarctica's airmass is very dry, very little
snowfall. Most of the place has had about 20 centimeters of snow over
the past 50 years.

  Snow or ice can be blinding no matter the direction.

True on average of course but the coastal regions get around 40cm
while the plateau gets 5cm or so.
