Mars Anomalies Sol 721 - Building-Craft or trick of light?

Another interesting anomaly has been found on Mars by the Mars Curiosity rover on Sol 721. Could this be a building, a craft or is just a nice rock?

Triangle UFO Craft captured over San Antonio, Texas - January, 2015

A new video with a triangle-shaped craft flying across the night sky above San Antonio, Texas, was captured by Billy Martinez.

''TRIANGLE U.F.O. CRAFT Billy Martinez San Antonio 1-17-15...craft occupying air space in San Antonio airport without doubt!!! This is definitely in a no fly zone, craft had 'NO RUNNING LIGHTS' and was completely black.  Triangle craft was about 10 to maybe 15' in height. The consistent steady lights are consistent with known ET CRAFT. Lights do not alternate from color. They are 'ULTRAVIOLET' which is why to the naked eye they reflected no light. Only once recorded are you able to see lights. ET craft made absolutely 'zero noise'!!! I am in direct contact with them!!!''
