Up, up and away!
The US FAA handles over 16 million flights per year, with a daily traffic of almost 3 million passengers and 120 million pounds of freight. That means there are a lot of planes in the air!
And if you take enough sky photographs, several are bound to photobomb you sooner or later.
During the day, jets may leave thin lines of clouds from their contrails across the sky. This is due to their hot, humid exhaust mixing with the high, thin atmosphere.
At night, their blinking transponder lights can stretch all the way across an image. Sometimes it adds an interesting line across the photo. Usually it is a nuisance. Shooting late at night and pointing away from popular flight paths can help.
How many airplanes are overhead right now?
Find one in the sky, then use the link below to see if you can figure out which one it is.
