Motorsport: British F4 racing driver loses both legs after horror Donington Park crash

More than half a million dollars has been donated to help a young British racing driver who has had both legs amputated after being involved in "one of the most horrific crashes motorsport has seen".

Billy Monger, a 17-year-old Englishman, was left fighting for his life after his car collided with a Finnish rival's during a British F4 race at Donington Park on Sunday.

On-board footage from a camera on Monger's car showed him seeming to run into the back of Patrik Pasma's stationary car in the FIA-sanctioned series. After being trapped in his car for an hour and a half at the central England circuit, Monger was airlifted to a hospital in nearby Nottingham.

Incredibly, Pasma, on the other hand, was virtually unharmed.

British F4 officials say Monger is in a "critical, but stable condition," having had both legs amputated while in an induced coma.

"Due to the injuries sustained and despite every effort, Billy has sadly had both lower legs amputated," they said in a statement.

"He has been kept in an induced coma while undergoing surgery, from which he is expected to be woken in the next few days."

Monger's family is seeking donations to fund the "care, treatments and therapies" the teenager now requires "to return to a full and active life."

By this morning, the total had reached £302,000 ($548,000) after it began with a £260,000 target.

"Having always been a fighter Billy has already overcome big hurdles in his career," the family said on the fundraising website JustGiving, which described the incident as "one of the most horrific crashes Motorsport has seen."

"Struggling for budget Billy has fought his way into top-flight motorsport, however, we now need your kindness and support to help give Billy and his family the best chance to fight these injuries that will affect Billy's life so massively."
