LONG BEACH, California (AFP) - Excited, nervous, terrified - just three emotions described by a group of US teachers about to take a dizzying weightless flight all for the cause of science, naturally. The 30 classroom professionals donned blue astronaut jumpsuits to defy gravity in the skies above California, in a project designed to help them capture the imagination of young science students. On the back of her jumpsuit, teacher Michelle Luke taped a drawing made by her pupils at Manhattan Beach Middle School, southwest of Los Angeles, showing two figures taking a giant weightless leap into space. But with only a couple of hours to go before the flight, her smile was still a little tense. I expect to see a lot of crazy things happening and do things that Ive never done before, she said at Long Beach airport, south of LA.
