Crash Avoidance Tips From NASA

From watching whales to flying through volcanoes, remote-controlled aircraft are becoming a popular research tool. Now NASA has some lessons to share with researchers, pilots and hobbyists who launch unmanned vehicles into the sky.

"Crash Course," a new ebook, details remotely piloted research vehicle and unmanned aircraft system mishaps and their causes, consequences, resultant corrective actions, and lessons learned, according to a NASA statement.
