Austrian extreme sportsman Felix Baumgartner, who died last week in a paragliding accident, was alive when his motorized paraglider descended but was killed upon impact, the Italian public prosecutor's office said on Tuesday.

Felix Baumgartner, the Austrian extreme adventurer who hurtled to earth from more than 24 miles high in 2012 and became the first human to break the sound barrier while free-falling, died on Thursday in a paragliding accident along the Adriatic coast in Italy. He was 56.
