UFO like orb caught during Air show in San Diego

On October 3, 2015, a father and his son were watching an air show in San Diego (California, USA). With his cell phone, the son has photographed a curious orb like UFO in the sky…

Witness statement:

On 10/03/2015, we were at the Mir Mar Naval Air Show watching all the different aircraft. 3:53 pm the french jet team was performing their stunts. My son who was with me said what is that? He grabbed his camera cell phone and took these pictures. It was hot and sunny so we did not really look at the pictures until we got to our hotel rooms. If you look close, the lights on the cylinder casts a shadow from the sun below. It seems the object ejects a contrail center left towards the sun on the bottom.
