SpaceX, NASA and U.S. Air Force personnel completed full-scale joint recovery trainer exercises to prepare for and ensure crew safety in the unlikely event of a rescue scenario. A full-size model of the spacecraft was used during rescue training. The Rescue Trainer was lowered into the Indian River Lagoon near NASA's Kennedy Space Center so that Air Force pararescuers and others could learn techniques for quickly reaching the spacecraft and supporting the astronauts onboard. SpaceX followed up the rescue and recovery testing in the Atlantic Ocean with spacesuit-clad astronauts and personnel who will assist upon return to Earth. The company will continue these training exercises in 2018.
