Divers looking for the wreckage of a World War II airplane last spring actually found part of the destroyed space shuttle Challenger. A large piece of the spacecraft was discovered at the bottom of the Atlantic Ocean off the coast of Florida. The site is not far from the U.S. space agency NASA’s Cape Canaveral launch area. NASA confirmed the discovery on November 10. The piece is from the space shuttle that exploded shortly after liftoff from Cape Canaveral on January 28, 1986. The last time anyone found part of the Challenger was in 1996. Seven people died when the Challenger exploded. Christa McAuliffe, a school teacher from New Hampshire, was part of the crew. An investigation of the accident found a faulty part in the right rocket booster caused the Challenger explosion.
