Delta flight 4858 was a routine flight from Southcoast to desert airport. The A320 was flying ok until it mysteriously lost all control. The plane banked, pitched, and rolled uncontrollably. The plane was not designed to fly like this and it put the airframe under to much stress. The A320 vertical stabilizer broke off first and the rest of the plane followed. The A320 fell into the ocean in pieces. All 112 people on board were killed.
