"November 1 1911 Lieutenant Giulio Gavotti flew an Austrian-designed Taube aircraft over the Taguira Oasis on the Turkish front. Extracting the pins with his teeth, he threw four 4.5lb grenades from about 300ft onto the troops below. The grenades managed to achieve very little but the incident caused an international enquiry and provoked protests from the Turks about the indiscriminate nature of the attack. The first true bomb, with fins and a detonator, was designed by a Bulgarian soldier, Simeon Petrov, in 1912. In the Balkan War against Turkey that autumn, two bombs were dropped on a Turkish railway station from an Albatros aircraft. This was the first bomber aircraft and the first true bombs, whose design became standard during the World War I."
Not one of my usual sources (!) , but in this case I think fairly reliable and easy to hand:
