Fast streaking object in the sky with high-pitched whistling sound and NO contrails

One day I was waiting for my friend to finish helping his dad fix his gocart and I was just wondering in his neighbor's backyard out of boredom. Just then I heard the sound of a jet, but I listened more carfully and it sounded like a jet but with a high-pitched whistling sound with it. Then I finally saw it, it was streaking across the sky so fast that I knew ammediately that it couldn't be a jet. The weird thing was is that it had absolutely no contrails at all. But, even though this ordeal lasted around 5 minutes I didn't think about telling anybody else because I was so fascinated with it at the time.
