January 12 2013 – Tijuana, Mexico. These strange sounds from the sky were recorded in Tijuana, Mexico on the 12th of January 2013. They are similar to a plane flying by, to a motor engine. As you can see, no wind was present during the recording (look at the trees, they are not moving). Maybe is this the city noise, which can be in larger cities pretty loud. Thank you for the video!
