I was standing out in my yard doing photography for my business, I look towards the east and about at 10,000ft was fast moving object that looked like brown sphere coming from the south at a high rate of speed heading north. My initial attempt was too rule out Buzzers that we do have here in Florida but they usually circle in thermal vents during the daytime. but this object was heading north in straight direction. Twenty minutes later the same object is coming from the north heading south. I literally ran to catch up with it in order to see the direction it was going, it was probably traveling faster than any commercial jet, there was no sonic boom, no air radiating off the craft as you would see any fighter jet when it breaks the sound barrier
