On February 2, King Vajiravudh paid an unexpected visit to the race track. After inspecting the
machine and conversing with the pilot, he was given a special demonstration, during which Van den Born dipped his wings in a smart
salute as he passed His Majesty.
Summing up the historic event, the Times commented, "Siam is fortunate in making, among Far
Eastern countries, early acquaintance with the achievement of modern aviation. The first Bangkok meeting boasts of only one aviator,
but he is an expert and therfore the fact that he is alone matters much less than might have been expected...No attempt has been made
to break records but the aviator has certainly demonstrated that aeroplaning is a practical thing, and nothing could have been more
graceful than the way the machine was made to salute the King on the occasion of His Majesty's first visit to the ground. Aeroplaning, it
is now everywhere recognized, is not an acrobat's trick, but a sport which is becoming increasingly practical."
