A millionaire fitness firm founder was killed attempting a British land speed record.
Zef Eisenberg, who launched Maximuscle, died at Elvington Airfield, near York, where in 2006 ex-Top Gear presenter Richard Hammond crashed.
Emergency crews were called after reports of a “serious collision” at about 16:30 BST on Thursday.
Guernsey-based Mr Eisenberg, 47, was involved in a “near-death” 230mph crash at the same airfield in 2016.
His family confirmed his death to the BBC.
North Yorkshire Police said an investigation into the crash was ongoing.
Mr Eisenberg ran the Madmax Race Team, which attempts speed records with motorbikes and cars.
Before his previous crash, in which he suffered 11 broken bones including his pelvis, he had set other speed records at the airfield.
He returned to racing in 2017, despite concerns he would never walk again.
In 2019, Mr Eisenberg set the record for the “flying mile” at Pendine Sands in Wales, stealing the crown from actor Idris Elba, who himself had broken the record in 2015, after it had stood since 1927, when Sir Malcolm Campbell set the pace.
He also holds a Guinness world record for exceeding 225mph (363kmh) in a turbine-powered motorbike in 2015, as well three FIA records for speeds achieved on an electric motorbike.
The businessman, who left school after his GCSEs, founded sports nutrition company Maximuscle in 1995. It was sold to pharmaceutical giant GlaxoSmithKline in 2011 for £162m.
Elvington was an RAF station until 1992, and has become a popular motorsports venue since entering private ownership.
It has hosted dozens of world record attempts, and is also used as a filming location.
