Why India by Aeroplane?

The Director of Civil Aviation, Sir Sefton Brancker, needed to travel to India to inspect the possibility of establishing airship facilities.

The R80 airship, first flown on 19 July 1920

The de Havilland Hire Service quoted a return price of £1,450 but a first class ticket on a P&O liner would be half that amount.  

Alan Cobham felt the Director of Civil Aviation should not have to travel by P&O liner because it was the cheaper option.  So he raised the additional £750 needed to travel by aeroplane from the aviation industry. 

Alan Cobham realised the importance of this momentous flight to the future of civil aviation.
