Although it was reported that their flights were the result of a wager between the two men, this was subsequently denied.The following week, on 26 April, Vivian Hewitt successfully completed a flight between Holyhead and Dublin, landing in the Phoenix Park.
Interviewed by the press, he expressed the view that Allen had been insufficiently experienced as an aviator for a flight of such difficulty.On 24 June 1912, the High Court in London made an order that Allen should be presumed to have died on or after 18 April 1912.
A consulting engineer by profession, Allen left an estate valued at £6,923 15s 8d.
At the time of his death, Allen was being sued in the English courts for the recovery of a portrait of Lady Anne Ponsonby by Thomas Gainsborough, which he had sold at Christie's for 8,300 guineas (£8,715).
On 11 February 1913, after a seven-day trial, the jury returned a verdict for the defendants, including the executors of Allen's will.
