一架以色列F16战斗机坠落在约旦河西岸，飞行员未能幸免。

The 21-year-old pilot, Assaf Ramon, was the son of Israel's only astronaut, Ilan Ramon, who died in the explosion of the space shuttle Columbia in 2003.

Sunday's crash took place in a hilly area south of the city of Hebron, military officials said.

The jet was on a routine training flight, they added. There is no word on why it went down. Search and rescue crews are at the scene.

Ilan Ramon - who was a former fighter pilot himself - is regarded as a national hero in Israel, and media broke into their normal broadcasts to report his son's death.

An unidentified Palestinian told Israeli TV that the plane had flown low over the southern West Bank before crashing.

"There was a huge fire," the eyewitness² said.

Lt Assaf Ramon graduated from the Israeli air force pilot's course earlier this year.

The military statement said he had excelled³ in（在……方面胜过） his training course, and had been given his wings by President Shimon Peres.

The Columbia disaster occurred on 1 February 2003.

The space shuttle disintegrated⁴（粉碎，瓦解） during re-entry over the US state of Texas, killing all seven astronauts on board.
