I was on a charter bus around 8 p.m. the bus had gotten a flat tire in barstow on a dark part of the freeway.The lights in the bus were off and there were no lights in the area outside so nothing could have reflected or interfered with our outside view. We just started on our way again on the freeway. My mom told me to look out at the shooting star, when i turned the light was larger than a typical shooting star and was yellow orange and very bright and hovered in one spot only just above the horizon. A few seconds later it shot straight in up into the sky and disappeared. I found it interesting how when it shot up it was a completely straight vertical path at a speed slightly slower than lightning. There was no trail and soon after it shot up it disappeared. I felt confused at first and then i realized i what i had just witnessed.
