Prepare For Landing, Gregory A. Dilisi, Richard A. Rarick

An ad-hoc experiment that the author constructed during a flight to measure the airplane's motion during its descent is described. The apparatus comprised a pendulum formed from a USB memory stick with a string attached, which was fixed to the airplane's window using medical tape, with a Post-it note used as a backdrop for measuring the position of the pendulum. Pictures of the pendulum were taken with a digital camera, so that the angular displacement could later be measured using a computer. From a spec sheet that lists a range of performance and flight parameters of the airplane ...

The writers describe their experience of a flight aboard NASA's C9 so-called Weightless Wonder aircraft. To celebrate the 2005 World Year of Physics, NASA, the American Association of Physics Teachers, and the American Physical Society co-sponsored a contest to select teams of high school students and their mentors to fly an experiment aboard the aircraft, which simulates microgravity by conducting a series of parabolic maneuvers. In January 2005, the writers learned that their experiment, which studied how thin strands of liquid suspended between movable supports would respond to entering and exiting microgravity, had been selected as one of 6 ...
