A British scientist has died in a base jumping accident in the Middle East.
Dr Angelo Grubisic, 38, was taking part in a planned jump in Saudi Arabia on Tuesday when he was killed.
The astronautical engineer had led a wingsuit design team at the University of Southampton and was crowned a British wingsuit champion in July.
Dr Grubisic had previously worked on spacecraft propulsion for both NASA and the European Space Agency.
His family described him as "phenomenally talented" in a statement.
They added: "Angelo lost his life doing what he loved the most, wingsuit base jumping, and we want to ensure his achievements and ambitions are known to the world and to celebrate the mark he made on all of our lives.
"Angelo captivated the hearts and minds of every single person who was privileged to meet and work with him.
"'The candle that burns twice as bright burns half as long' has never rang more true to the family and friends Angelo had across the world."
His sister said: "I can’t even believe I am writing this, but my brother sadly lost his life yesterday doing what he loved.
"Words cannot even begin to explain the pain we all feel, it still feels like a bad dream and that I’m going to wake up from it.
"He truly was an Amazing guy and brought so so much to this world and had so much more to give.
"What he achieved in his short life was incredible, and there was nothing he couldn’t do and I mean nothing!
"The guy had it all. I just wish we had more time with you bro.
"Fly high my beautiful brother, until we meet again"
In 2015 he set up the Icarus project which was attempting to design a wingsuit to break world records while improving safety.
Earlier this year he also gave evidence into the death of fellow wing suit jumper Rob Haggarty who died after he .
