Location: NA, Missouri

I was in a plane flying from Vegas to Indianapolis (via spirit airlines). I was trying to nap when the plane seemed to slow down suddenly so I opened my eyes and a few moments later I saw something out of the corner of my eye out the window. I had to turn my body to look back at the object that had flown past us. It looked like a metal sphere going at high speeds before it disappeared into the clouds. I looked up the flight logs and the plane was consistently flying at 36,975-37,025ft the whole trip until this moment it dropped to 35,950ft. It was at 18:03pm (Vegas time).
