Wilbur Wright cheque book flown at Shuttleworth

Wilbur Wright‘s cheque book is insured for 300,000 USD, presented to me prior to displaying the Extra 330SC at Shuttleworth on the 20th July. To fly with the cheque book belonging to the “inventor” of aviation from 110 years ago is quite a moment.

Did Wilbur and Orville imagine what would be possible given engine power and structural materials of this age what would be possible?.
