An unusual sight was seen in Philadelphia skies on Sunday, July 5. Hector Garcia captured what appears to be a small, cloud-like mass floating just above the rooftops in the Tioga neighborhood. While some have speculated on the possibility of a UFO, other explanations raised include a big bag, weird cloud, and soap suds, according to the www.huffingtonpost.com/2015/07/08/shape-changing-ufo-philade ; target="_blank">Huffington Post.
