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

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. 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. Above quotes from NZ TV which also has footage of the NVG view. Ned |
