McMURDO STATION, ANTARCTICA (December 10) -- Flying over any town is an unusual request and McMurdo is not an exception. When I asked if we could fly at 1,000 feet over town, I was greeted with skeptical looks. McMurdo is nestled beneath a valley between Observation Hill and Hut Point. The request sounded like a boondoggle. I had to explain that to ensure the laser is correctly aligned with the aircraft frame, we have fly over pointed roofs. Our Reigl laser is developed in Austria where there are ample pointed roofs for calibrating the instrument. There are not many pointed roofs in Antarctica so flying over McMurdo seemed like the obvious answer.

For about a decade, public health officials have been aggressively pushing colonoscopy, a procedure that inspects the colon for growths using a tube and camera, as the gold standard for detecting tumors while they're still treatable.
