On Tuesday 31^st July 1894 the American-born inventor and engineer Hiram Maxim (1840-1916) was testing the latest version of his flying machine at his home, Baldwyn’s Park near Bexley in Kent. He had laid out a steel track, 1800 feet in length, in order to run the machine in a straight line between the trees of the Park.

On the final attempt of the day, having increased the pressure of the machine’s steam boiler, the wheels rose from the track and it flew for eight seconds at a speed of 45 miles per hour before crashing to the ground. The flying machine weighed more than three tons. Maxim was on board along with two mechanics, Arthur Guthrie and Thomas Jackson.

Should this be recognised as the first heavier-than-air flight, nine and a half years before the Wright brothers’ flight at Kitty Hawk, North Carolina, on 17 December 1903?

William McGregor Ross (1876-1940), a young admirer of Maxim who also became an engineer, thought that Maxim’s achievement had not received the recognition it deserved. He used every opportunity to correct this and a collection of papers and photographs, recently donated to the Bodleian by his grandson, records the efforts he made until the end of his life. William was educated at Southport Grammar School and began keeping a diary from an early age, recording in meticulous detail and tiny handwriting the events of his daily life. His diary of 1892, when he was 16 years old, reveals his interest in flying machines and in August he wrote to Hiram Maxim asking for advice on screw propellers.

Maxim replied (sending ‘several wrinkles’, i.e. tips or hints) and a lifelong friendship developed between them with Maxim and his wife Sarah supporting William’s interest in engineering, which he went on to study at Liverpool and Dublin Universities. In September 1892 William was invited to visit Baldwyn’s Park where he saw the development of the flying machine which Maxim had been working on for a year, eventually testing the thrust of over 200 types of propeller before the flight in 1894.

William’s diary entry for 15 September 1892 records the running of the machine on the track through the Park, reaching a speed of 27.5 miles an hour. He notes that photographs were taken after the experiments and the donation to the Bodleian includes one of the photographs of young William together with Hiram Maxim on board the flying machine.

William did not witness the short flight in 1894 – his diary records that he was in Southport on the day – however his interest in flying machines continued as evidenced by a letter full of questions to Mrs Maxim in February 1899.

Maxim continued to develop his machine but came to realise that powering it by steam, requiring boilers and water, added excessive weight and his experiments came to an end.

Following Hiram Maxim’s death in 1916 William continued to correspond with Sarah Maxim and in 1934 made particular efforts to have the 40th anniversary of the flight recognised, writing to the national press, scientific journals, the BBC and film companies. He repeatedly argued that any history of aviation excluding Maxim’s role in the development of heavier-than-air flight was incomplete and pointed out that he held the altitude and duration records for 9 years and 139 days and the weight record for even longer. The newly available papers present William’s observations on the remarkable events at Baldwyn’s Park on their 130th anniversary.
