A British-built car is due to be tested in preparation for a challenge to beat the world steam-powered vehicle land speed record.
It was meant to be tested last month, but technical problems hampered the launch and it was left sitting on the track at a Ministry of Defence site in Hants.
The rig's water filter let impurities into the water system and a build-up then resulted in a blockage, a problem the team behind the British Steam Car had not come across before.
The car and team have returned to the MoD's Thorney Island facility in Emsworth for what is expected to be their last test in public before this summer's challenge.
The British Steam Car team includes test driver Don Wales, the nephew of late Donald Campbell and grandson of Sir Malcolm Campbell, who managed more than 20 water and land speed records between them.
The current steam record is 127mph and was set 103 years ago by American Fred Marriott who drove a Stanley steam car at the Daytona Beach Road Course in 1906.
Weighing three tons, the British Steam Car is due to undergo a full test of its capabilities, including its steering, parachute deployment and braking systems, as a dress rehearsal for the record attempt in the United States.
