Flying lesson

六月 2, 1995

Students who want to take part in experiments in conditions of weightlessness are invited to submit proposals to the European Space Agency by June 16. In November, winners of the competition will be able to fly on an aircraft which will travel in a parabola, creating microgravity for a few moments when it plunges. Apply to "Parabolic Flights", 8, Rue Maria-Nikis, 75738, Paris Cedex 15, France.
