This was taken about a week ago in Bryant Park during lunch time. One of those blue sky day. Perfectly blue and cloudless sky. Hardly no wind. All conditions required for skywriting.
Skywriting is this advertising medium using a small airplane, able to expel special smoke during flight. By flying in certain patterns, it creates writing readable by someone on the ground. Since the puffs of smoke dissipate very quickly into the atmosphere, the message is usually limited to one or two words. Winds cause the writing to blur, usually rapidly. To avoid that, special techniques have been developed to write in the sky in a dot-matrix fashion, which is what you see in this picture. It seems so cutting-edge, right? I was surprised to learn that skywriting was actually developed in 1922 by a pioneer English aviator, J. C. Savage.
Can you figure out what was written up there? I could not. This spring though I saw something similar in the Upper West Side on a beautiful Sunday afternoon with perfect blue sky. It read "wow". A few minutes a second word was written: "wow". Then a third: "wow". Wow, wow, wow - that's a good message, no?
