What members of royalty were in attendance to witness the "miracle" as noted in the biography, The Wright Brothers?

In the last week of February, King Alfonso XIII of Spain came to witness the “miracle.” Alfonso’s only special request was that he be allowed to see one of the aviators who Wilbur had trained pilot the Flyer. He was amazed the new pilots had learned so quickly. Edward VII, the King of England also came to be a spectator to the amazing event. The King was given a tour and taken inside the shed to see the plane. Wilbur apologized for its worn appearance. As Wilbur took off in the Flyer, Orville explained its workings to King Edward.
