At the moment the operators name is unknown but I expect it will become common knowledge within hours. Looks like it was a DJI Phantom and I must say that I am very impressed that it could take the hit and fly on. If it had not and been found by somebody in authority it could have had a very different outcome for the operator.
The Sultan Ahmed Mosque has one main dome, six minarets, and eight secondary domes. The design is the culmination of two centuries of Ottoman mosque development. It incorporates some Byzantine Christian elements of the neighboring Hagia Sophia with traditional Islamic architecture and is considered to be the last great mosque of the classical period. The architect, Sedefkâr Mehmed Ağa, synthesized the ideas of his master Sinan, aiming for overwhelming size, majesty and splendour.
