WITNESSES heard the screams of three men trapped in a campervan after it crashed off John Renshaw Drive and caught alight, court documents tendered to East Maitland District Court stated.
One of the rescuers smashed a window and helped drag one of the men free from the burning vehicle, but just as the rescuers were about to smash another window and hopefully cut free the two remaining occupants an explosion erupted inside.
The screaming stopped.
Adam John Bonner was told yesterday that he will be jailed for causing the crash that claimed the lives of Swiss tourists Hans Peter Heim, 59, and Jean-Pierre Descombe, 62.
Mr Heim and Mr Descombe had driven with Han-Ulrich Mueller from Cairns and were on their way to Melbourne when Bonner, 33, of Waran Road, Whitebridge, lost control of his Holden Commodore SS in heavy rain at Black Hill on November 1, 2010.
Bonner's passengers told police that the Commodore had "kicked out" at least once on the wet road before Bonner lost control and the Commodore spun and slid across a median strip into the path of the campervan.
The campervan rolled onto its side and slid down an embankment before it caught alight.
Bonner previously pleaded guilty to two counts of dangerous driving occasioning death. His barrister, John Booth, said that while Bonner was travelling below the speed limit, he was driving too quickly.
Bonner, a P-plater, was also driving a car that was too powerful for his licence.
Judge John North said Bonner will be jailed, but he continued Bonner's bail until the sentence is handed down later this month.
