A widebody cargo plane hauling packages for Amazon abruptly plunged out of the sky and slammed into a bay on Saturday as it was preparing to land in Houston. All three people on board were killed.

The Boeing Co. 767-300, operated by Atlas Air on a flight that had departed from Miami, disappeared from radar and lost radio contact, landing in a bay about 40 miles (64 km) from Houston¡¯s George Bush Intercontinental Airport, said Robert Sumwalt, the National Transportation Safety Board chairman who¡¯s leading the investigation.

The jet fell thousands of feet in seconds after what had been a routine descent, according to Sumwalt and the flight-tracking website FlightRadar24. Human remains were recovered at the scene, the FBI¡¯s Houston office said in a tweet.
