Icarus Aerial Filming, one of the top commercial drone piloting companies in Greece, created this spectacular aerial video of the island of Sifnos. Sifnos is part of the Cyclades group of islands in the Aegean Sea, which includes Mykonos, Milos, Naxos, and other well known Greek islands. The stunningly beautiful island is about 15 km (about 9 mi.) long at its widest point, and it has a permanent population of about 3,000. It is known in part for its summertime religious festivals.
