Single large bar of light traveling at very high speed perpendicular to the light.

A group of college students and myself the instructor witnessed a very large light moving rapidly across the sky. I have witnessed many space X satellites and this was not a group of objects but a single one. It was also traveling perpendicular to the bar of light. It was traveling lower than satellites and a plane was spotted a few minutes later in a similar area. The plane had typically lighting and was less that a 10th of the UFO. It was bigger than any aircraft that I am aware of. It had a single large blue light for the entire width and a faint grey outline was visible. We had time to get phones for pictures and videos and even tell others in their tents to look. It hit a clear part of the sky and disappeared without any trace or trail or indication of direction. It was actually one of the strangest experiences that myself or any of the students had ever had.
