On April 3, 2013, a person was in Wanaaring (Austalia) and he took a picture of a road. A few weeks later, he noticed a possible UFO on it.

Witness statement:

We were pig hunting in Wanaaring, NSW Australia on approximately 3/4/2013, 2pm.
We stopped to take a picture of a road sign because town was named the same as his sister
I was standing directly behind the person that took the photo and I saw nothing. The photos were taken with at least a 2 second pause between them. No one saw nothing at all during the trip the object in the photo was noticed about a week after.
