Have a good start to the new week, everyone! Today I have a riddle for you. One day, while walking on a deserted beach in Goa, I looked up at the sky and saw something flying in the distance. Until it disappeared, I took photos over and over again, trying to catch it in the lens, zoom in and get a closer look... I have some very good pictures where you can get a good look at it. But I want you to guess who or what it is? Whoever guesses first, I'll give you their name when I post the rest of the pictures of this something. India, Goa, Morjim, 2018
