June 24, 1982 - During a calm ight to Australia, smoke starts lling the cabin of a passenger jet. At the same time, the flight crew witness a bizarre shower of brilliant white sparks hitting their windshield. Within moments, the four engines of the 747 shut down. Just seconds before crashing into the Indian ocean, the engines roar back to life. The terrifying ight changes the way pilots are trained and alters forever the understanding of how volcanoes can affect passenger jets. (iTunes)
