Every year a group of European scientist get the chance to experience weightlessness in an initiative from ESA. They are able to conduct their experiment as they go up ina special plane that can create the same conditions as in space.
In parabolic flight, the aircraft is put into a specially-shaped trajectory that provides free-fall, or weightlessness. This weightless experience, other than the duration, is exactly that experienced by astronauts on orbital missions. Each flight begins by having theaircraft perform an aerobatic manoeuvre, which starts from level flight, and pitches up to apporximately 45 degrees nose-hight and wingls level subjecting the passengers to a 2 g pull up lasting about ten seconds. After that, the aircraft engines are powered back and the airplane is launched into the same parabolic trajectory that a ball would follow, providing everyone inside the plane with around twenty-five to thirty seconds of total weightlessness for experimentation puroposes.
