It is believed that this aeroplane was the first aircraft Robert Blackburn built and it was known as "Monoplane No.1". On 24th May 1910 it was been test-flown on the sands between Redcar and Saltburn when, during one of the test runs and whilst flying near Marske by the Sea at a height of only two or three feet above the sand a turn was made. The aircraft sideslipped and it skidded into a hole. The tyre of one of the wheels came off and though the pilot cut the ignition he was thrown from the aircraft but was not injured. The aircraft sustained damage to the left wing.
Pilot - Mr Robert Blackburn, of Leeds.
