Sir, - Kevin Myers (April 11th) has told us that when the late British Dowager Queen was born "no heavier-than-air aircraft had ever left the ground".
Please tell him about Otto Lilienthal (1848-1896), who flew gliders from 1891 more than 2,000 times until a crash killed him in 1896. - Yours, etc.,
S. UA Conchubhair, Uarβn M≤r, Gallimh.
