I saw approximately 5 aluminum/silver objects flying at high speed from south to north over the Sandia Mountains

While leaving my home to walk the dog, I noticed the sky was dark and stormy looking. Not wanting to get caught in the rain, I proceeded to look West, high in the sky, over the Sandia Mountains. I noticed a Aluminum or Silver dot crossing the sky from the South to the North. It was very high in the sky and moving at what appeared to be a high rate of speed. It was moving at such a speed it didn't appear to be a Commercial Airliner. All of a sudden I saw several more Aluminum or Silver type dots a little behind it. All the objects were moving at the same speed and appeared to be the same shinny dots. I figured perhaps they were Military Jets. I didn't hear any noise or see any con trails. There were about 5 and possibly 6 objects and they were spaced apart at different distances from each other. It didn't appear to be a formation of Military Jets. I grabbed my phone and tried to get a video of the objects, but was unsuccessful. The objects then disappeared into the clouds heading North. The entire event only lasted for less than a minute. There is an Air Force base south of my location and perhaps they were military jets flying North over the mountains..
